Mastering NetZero Message Center Login Access and Security

Master NetZero Message Center Login System: Core Components and Security Architecture

The system employs a three-tiered authentication framework combining credential verification, behavioral analysis, and conditional multi-factor authentication (MFA). Each tier operates independently yet synergistically to mitigate risks such as credential stuffing, brute-force attacks, and session hijacking. The first layer involves standard username/password validation, enforced with dynamic complexity requirements (e.g., 14+ characters, mandatory special symbols, and periodic rotation policies). The second layer introduces CAPTCHA-based challenge-response mechanisms, dynamically adjusted based on geolocation, device fingerprinting, and historical login patterns. The third layer triggers time-based one-time passwords (TOTP) or biometric verification (e.g., fingerprint or facial recognition) for high-risk transactions or repeated failed attempts, aligning with NIST SP 800-63B guidelines for digital identity proofing.

Authentication Layers and Security Protocols

Blockchain-anchored audit logs record all authentication events, including timestamps, device metadata, and cryptographic hashes of failed attempts, enabling forensic analysis. The system also integrates Real-Time Blackhole Lists (RBL) to block known malicious IPs and AI-driven anomaly detection (e.g., sudden login volume spikes or atypical device usage patterns) via NetZero’s proprietary Threat Intelligence Engine.

User Interface Elements and Functional Roles

1. Authentication Panel
   • Username Field

     Accepts alphanumeric strings with optional hyphens/underscores (max 64 characters). Enforces case sensitivity and rejects SQL injection patterns via server-side validation.

   • Password Field
     • Implements dynamic masking (shows/hides characters on hover) to reduce phishing risks.
     • Triggers real-time strength meter with color-coded feedback (red for weak, green for strong) based on entropy scoring.
     • Supports passwordless login via FIDO2-compatible hardware keys (e.g., YubiKey) for enrolled users.
   • CAPTCHA Module

     Uses adaptive CAPTCHA (e.g., image-based for high-risk logins, text-based for low-risk) with hCaptcha Enterprise integration to prevent bot automation. CAPTCHA challenges are regenerated per session to thwart replay attacks.

2. Conditional Verification Module
   • Multi-Factor Authentication (MFA) Trigger Conditions

     Condition	Response	Security Measure
     First-time login from new device/IP	TOTP via SMS/email	One-time 6-digit code valid for 5 minutes
     3+ failed attempts within 10 minutes	Biometric prompt + IP lockout (15 mins)	Facial recognition or fingerprint scan required
     Login from high-risk geolocation (e.g., VPN/jailbroken device)	Hardware key or push notification approval	FIDO2 or Google Authenticator push

   • Session Token Display

     A 16-character alphanumeric token (e.g., `X7K9-P2Q4-M1R6-T8Y2`) is generated post-login for manual verification in customer support interactions. Tokens expire upon session end and are logged in immutable ledger format.

3. Post-Login Redirect Handler
   • Validates user role (e.g., consumer, administrator, auditor) to route to appropriate dashboards.
   • Injects CSRF tokens into all subsequent requests to prevent cross-site request forgery.
   • Enforces SameSite cookie attributes to mitigate session hijacking via cross-site scripting.

Step-by-Step Access Procedure and Pre-Login Checks

1. Pre-Login System Requirements
   • Browser Compatibility

     Supports Chrome (v90+), Firefox (v85+), Edge (v91+), and Safari (v14+) with WebAuthn and WebCrypto API enabled. Blocks Internet Explorer and outdated browsers via UA sniffing.

   • Network Requirements
     • Minimum bandwidth: 1.5 Mbps (upload/download) for CAPTCHA/image-based challenges.
     • HTTPS enforcement: Redirects HTTP traffic to HTTPS (port 443) with HSTS preloading enabled.
     • Proxy/VPN detection: Blocks logins from Tor exit nodes and datacenter IPs unless whitelisted for enterprise accounts.
   • Device Health Check
     • Verifies operating system patches (e.g., Windows 10/11, macOS Ventura+) via user-agent parsing.
     • Detects rootkit or jailbreak indicators using device fingerprinting (e.g., unique hardware attributes).
2. Login Workflow Steps
   1. Navigation to Portal

      Users access the login URL (`https://login.netzeroenergy.com`) via direct entry or embedded widgets in partner portals (e.g., utility provider sites).

   2. Credential Entry
      • Username/password fields auto-focus on mobile devices.
      • Password field includes auto-fill blocking to prevent credential leakage via browser managers.
   3. CAPTCHA Resolution
      • For high-risk logins, presents adaptive challenges (e.g., "Select all images with solar panels").
      • Allows manual CAPTCHA refresh if initial attempt fails.
   4. MFA Verification (Conditional)

      Security Features and Best Practices for Master NetZero Message Center Login

      The Master NetZero Message Center Login System employs a multi-layered security architecture to safeguard user credentials, communications, and system integrity. Advanced authentication protocols, real-time threat detection, and proactive user guidelines collectively mitigate risks associated with unauthorized access, credential theft, and phishing attacks. Below are the core security mechanisms integrated into the system, alongside actionable best practices for users and administrators to maintain robust protection.
      

      Multi-Factor Authentication and Advanced Authentication Protocols

      The login system integrates OAuth 2.0 with OpenID Connect (OIDC) for secure third-party authentication, reducing reliance on static passwords while enabling single sign-on (SSO) across authorized applications. Biometric verification—via fingerprint, facial recognition, or hardware tokens—is supported for high-risk sessions, aligning with NIST SP 800-63B guidelines for digital identity assurance.

      For enterprise environments, FIDO2-compliant security keys (e.g., YubiKey, Windows Hello) are recommended to prevent credential stuffing attacks. The system enforces context-aware authentication, dynamically adjusting security requirements based on:
      

      • User role (e.g., admin vs. standard user).
      • Geolocation (blocking logins from unexpected regions).
      • Device posture (verifying OS patches, antivirus status, and physical security).

      Key Security Principle:
      "Authentication should be as strong as the value of the protected resource." — NIST Special Publication 800-63-3

      IP Whitelisting and Network-Level Protections

      To prevent brute-force and distributed attacks, the system implements:
      
      • Dynamic IP whitelisting for frequent users, with alerts for deviations.
      • Geofencing to restrict logins to predefined regions (configurable per user).
      • VPN enforcement for remote access, requiring TLS 1.3 or IPSec encryption.

      For high-security roles, hardware-based network authentication (e.g., Cisco Duo, RSA SecurID) is enforced. The system logs all IP-based access attempts in SIEM-compatible formats (e.g., JSON, CEF) for forensic analysis.
      

      Example Threat Scenario:
      A user in New York attempts to log in from Moscow within 10 minutes of a prior successful login. The system triggers:
      1. Real-time alert to the user’s email/SMS.
      2. Temporary lockout until biometric re-verification.
      3. Incident ticket in the Message Center for review.

      Password Policies and Credential Hygiene

      The system enforces NIST SP 800-63B compliant password rules, including:
      
      • Minimum length of 12+ characters (no arbitrary complexity requirements).
      • Progressive enforcement: Passwords must be changed only after 90 days of inactivity or 3 failed attempts.
      • Breach detection: Blocks passwords exposed in Have I Been Pwned (HIBP) datasets.

      Users are prompted to:
      

      • Enable password managers (e.g., Bitwarden, 1Password) with master password protection.
      • Use passphrases (e.g., `"CorrectHorseBatteryStaple!"`) instead of complex but predictable patterns.
      • Avoid password reuse across services, with cross-platform monitoring via the Message Center.

      Password Attack Mitigation Techniques:
      

      Rate limiting: 5 failed attempts → 30-minute lockout.

      Account lockout with gradual escalation: 10 attempts → 24-hour lockout.

      Behavioral analysis: Flags rapid password changes or unusual typing patterns.

      Device Management and Session Security

      The login system evaluates device security before granting access through:
      
      • Endpoint compliance checks (e.g., Windows Defender, macOS Gatekeeper, Linux SELinux).
      • Certificate pinning to prevent MITM attacks via rogue CAs.
      • Session timeout policies:
      • Standard users: 15 minutes of inactivity → auto-logout.
      • Admins: 5 minutes → forced re-authentication.

      Users must:
      

      • Register trusted devices via FIDO2 or TOTP (Time-Based One-Time Password).
      • Revoke access to compromised devices immediately via the Message Center.
      • Use dedicated browsers (e.g., Firefox with uBlock Origin, Chrome with Strict Site Isolation).

      Device Hardening Checklist for Users:
      

      Disable autofill for credentials in browsers.

      Enable Full Disk Encryption (FDE) (BitLocker, FileVault).

      Disable USB autorun and Bluetooth pairing persistence.

      Install OS updates within 48 hours of release.

      Real-Time Threat Detection and Alerts

      The Message Center provides proactive alerts for suspicious activities, including:
      
      • Unusual login locations: Notifications include IP geolocation, ISP, and device fingerprint.
      • Multiple failed attempts: Triggers CAPTCHA challenges and admin alerts.
      • Session hijacking indicators: Flags unexpected device switches or IP changes mid-session.

      Users receive customizable alerts via:
      

      • Email (with DKIM/SPF/DMARC validation).
      • SMS (with AES-256 encrypted payloads).
      • Push notifications (via Web Push Protocol for browsers).

      Example Alert Workflow:
      1. User A logs in from Paris at 3:00 PM.
      2. User A attempts login from Tokyo at 3:05 PM.
      3. System response:
      

      Alert: "Login attempt from new location detected. Approve or deny."

      Action required: Biometric verification or SMS code.

      Log entry: "Suspicious location shift – IP: 203.0.113.45 (Tokyo) vs. 198.51.100.1 (Paris)."

      Phishing Mitigation and User Awareness

      Phishing attacks targeting NetZero users often employ:
      
      • Clone phishing: Fake login pages mimicking the Message Center URL (e.g., `netzero-login[.]secure-login[.]com`).
      • Credential harvesting: Malicious apps or fake "update" prompts.
      • Social engineering: Impersonating support via email or chat.

      The login system mitigates these risks through:
      

      • DMARC enforcement: Rejects emails from spoofed domains.
      • Link verification: HSTS preloading and certificate transparency logs.
      • User education alerts: Flags unusual email senders (e.g., `support@netzero-login[.]xyz`).

      Phishing Red Flags and System Responses:

      Attack Vector	User Action	System Countermeasure
      Fake login page (URL spoof)	Hover over link to check domain.	HSTS enforcement + DMARC failure alerts.
      Malware-laced email	Avoid downloading attachments.	Email sandboxing + AV integration.
      Smishing (SMS phishing)	Verify sender ID via Message Center.	SMS spoofing detection (e.g., `+1-555-NETZERO`).

      Technical Safeguards Checklist for Secure Login

      To prevent credential theft during login, users and administrators should implement:

      Network-Level Protections:
      

      • Use a VPN (e.g., OpenVPN, WireGuard) with split tunneling disabled for login sessions.
      • Enable DNS-over-HTTPS (DoH) (e.g., Cloudflare, Google) to prevent DNS spoofing.
      • Block JavaScript execution in login pages via NoScript or browser extensions.

      Network/Connection Error	Unstable internet connection (Wi-Fi/ISP issues). Firewall/proxy blocking Message Center access. DNS or VPN interference.	Test connection via ping messagecenter.netzero.com (replace with actual domain). Disable VPN/proxy or configure exceptions for the Message Center URL. Temporarily disable firewall/antivirus to isolate the issue. Switch to a wired connection or mobile hotspot for diagnosis.
      Account Suspended/Disabled	Violation of terms of service (e.g., fraudulent activity). Administrative action (e.g., policy updates). Unpaid subscription or service termination.	Review account status via the Message Center dashboard. Contact support with account details and suspension notice (if provided). Provide required documentation (e.g., ID verification for reactivation).

      Note: For errors not listed, capture the exact error message and screenshot before attempting resolutions. This documentation aids support in diagnosing complex issues.
      

      Password Recovery and Account Unlock Procedures

      Forgetting credentials or encountering account locks disrupts access but can be resolved via self-service tools integrated into the Message Center. The following outlines the verification-based recovery process and unlock mechanisms.

      The recovery workflow begins with identity verification to prevent unauthorized access. Users must provide:
      

      Registered email address or phone number.

      Account username or partial details (if available).

      Personal identification (e.g., last 4 digits of SSN, security question answers).

      Step-by-Step Password Reset:
      1. Navigate to the Forgot Password option on the login page.
      2. Enter the registered email or phone number associated with the account.
      3. Select the verification method (email/SMS) and proceed.
      4. Enter the 6-digit verification code sent to the chosen channel within 5 minutes.
      5. Create a new password meeting complexity requirements (e.g., 12+ characters, uppercase, numbers, symbols).
      6. Confirm the password and complete the process.

      Account Unlock for Locked Users:
      

      Automatic Unlock: Accounts locked due to failed attempts typically unlock after 15–30 minutes.

      Manual Unlock Request:

      1. Submit a support ticket via the Message Center’s Help Center or contact form.
      2. Provide:
      

      Account username or email.

      Description of the issue (e.g., "Account locked after 5 failed attempts").

      3. Wait for an email/SMS confirmation with unlock instructions (typically within 1–2 business hours).

      Security Best Practices During Recovery:

      Avoid using default or easily guessable passwords (e.g., "Password123"). Enable MFA for an additional layer of security. Never share verification codes or recovery emails with third parties.

      Network-Related Login Failures and Configurations

      Network restrictions often prevent access to the Message Center due to misconfigured settings, ISP throttling, or corporate policies. Below are diagnostic steps to identify and resolve connectivity issues.

      Pre-Login Checks:
      

      Internet Connection: Ensure a stable connection via speed tests (e.g., speedtest.net).

      Firewall/Antivirus: Temporarily disable security software to test if they block the Message Center domain.

      Proxy/VPN: If used, configure exceptions for:

      Domain: `messagecenter.netzero.com` (replace with actual domain).

      Ports: Typically 443 (HTTPS) for secure connections.

      Step-by-Step Network Troubleshooting:
      1. Test DNS Resolution:
      

      Open Command Prompt (Windows) or Terminal (Mac/Linux) and run:

      nslookup messagecenter.netzero.com

      - Verify the IP address resolves correctly (no "Server Failure" errors).

      2. Check Port Availability:
      

      Use `telnet` or `nc` (netcat) to test port 443:

      telnet messagecenter.netzero.com 443

      - A blank screen or connection indicates the port is open; errors suggest blocking.

      3. Review ISP Restrictions:
      

      Some ISPs throttle or block access to corporate portals. Contact ISP support with the error details.

      Use a mobile hotspot or public Wi-Fi as a bypass test.

      4. Browser-Specific Issues:
      

      Clear SSL state/reset network settings in browser preferences.

      Try alternative browsers (e.g., Chrome, Firefox) to rule out browser-specific conflicts.

      Corporate/Enterprise Environments:
      

      IT administrators may enforce pac files or proxy auto-configuration. Request exceptions for the Message Center URL from the network team.

      Use Fiddler or Wiresh

      Message Center Features Beyond Login

      The Master NetZero Message Center extends beyond authentication to provide users with a centralized hub for account management, security monitoring, and operational transparency. Beyond the login interface, the dashboard integrates critical functionalities—such as real-time notifications, billing alerts, and login activity tracking—that directly influence account security and user experience. Customizable alerts and audit trails enable proactive fraud detection, while lesser-known tools like trusted device lists and temporary access codes streamline secure access without compromising integrity.
      

      Message Center Dashboard Overview

      The Message Center dashboard consolidates essential account-related information into three primary tabs: Notifications, Billing Alerts, and Account Updates. Each tab serves distinct yet interconnected purposes, reinforcing login security by ensuring users remain informed of suspicious or critical activities.

      - Notifications Tab
      Displays system-generated alerts, including login attempts (successful or failed), password changes, and security policy violations. These notifications act as a first line of defense, allowing users to verify unexpected activity promptly. For example, an SMS alert for an unrecognized login location in a different country may prompt immediate action, such as revoking session access or updating credentials.

      - Billing Alerts Tab
      Tracks subscription renewals, payment failures, or service usage thresholds (e.g., data limits). While primarily operational, billing alerts indirectly support security by preventing unauthorized service access due to lapsed payments. Users can configure thresholds to receive warnings before exceeding predefined limits, reducing the risk of account suspension.

      - Account Updates Tab
      Aggregates profile modifications, such as email address changes or two-factor authentication (2FA) enrollment status. This tab ensures users are aware of configuration changes that could impact login security, such as a newly added recovery email or a disabled 2FA method.
      

      Customizing Notification Preferences

      Notification preferences in the Message Center allow users to tailor alert delivery (email, SMS, or push notifications) based on sensitivity and urgency. Proper configuration enhances account monitoring by ensuring critical events are communicated through the most reliable channel.

      To customize preferences:
      1. Navigate to the Settings or Preferences section within the Message Center.
      2. Select Notification Settings and choose alert categories (e.g., "Login Attempts," "Password Changes").
      3. Define delivery methods per category—prioritize SMS for high-risk events (e.g., failed logins) and email for administrative updates (e.g., policy changes).
      4. Adjust frequency thresholds (e.g., receive alerts only for failed logins from new devices).

      Example Configuration:
      

      High-Risk Alerts (SMS): Failed login attempts, password resets from unrecognized IP addresses.

      Moderate-Risk Alerts (Email): Successful logins from new devices, 2FA enrollment status changes.

      Low-Risk Alerts (Push Notifications): Routine account updates (e.g., profile modifications).

      > Best Practice: Enable notifications for all login-related events and use multi-channel delivery (e.g., SMS + email) to mitigate missed alerts due to channel failures.
      

      Viewing and Managing Login History

      The Login History feature provides a chronological record of all authentication attempts, including timestamps, device types, IP addresses, and success/failure statuses. This functionality is critical for fraud investigation and behavioral analysis.

      To access login history:
      1. Open the Security or Activity Logs tab in the Message Center.
      2. Filter records by:
      

      Timeframe (e.g., last 7 days, custom date range).

      Device Type (desktop, mobile, unknown).

      Location (country, city, or IP range).

      3. Review individual entries for anomalies, such as:
      

      Multiple failed attempts from a single IP.

      Logins during unusual hours (e.g., 3 AM local time).

      Devices not previously associated with the account.

      Filtering Example:
      

      Scenario: Suspected credential stuffing attack.

      Filter for failed logins within the past 24 hours, grouped by IP address.

      Identify IPs with >5 failed attempts and block them via the Security Settings tab.

      Generating Login Activity Reports

      For auditing or compliance purposes, the Message Center allows users to generate downloadable reports of login activity. These reports include detailed metadata (e.g., user agent, geolocation) and can be exported in CSV or PDF formats for further analysis.

      Report Generation Process:
      1. Access the Reports or Audit Logs section.
      2. Select Login Activity Report and define parameters:
      

      Date Range (e.g., monthly, quarterly).

      User Accounts (single account or group).

      Activity Type (all logins, failed attempts, or specific events).

      3. Download the report and analyze for patterns, such as:
      

      Unusual spikes in activity during non-business hours.

      Logins from high-risk countries (e.g., known for phishing hubs).

      Repeated access from corporate vs. personal devices.

      Use Case:
      

      Fraud Investigation: A report revealing 10 failed logins from a single IP across multiple accounts may indicate a brute-force attack.

      Compliance Audits: Export login logs to verify adherence to access control policies (e.g., "No logins after 10 PM").

      Lesser-Known Security Tools in the Message Center

      Beyond standard features, the Message Center includes advanced tools designed to balance convenience and security without sacrificing usability.

      - Temporary Access Codes
      Generate one-time-use codes for single sign-on (SSO) sessions, reducing reliance on permanent credentials. Ideal for shared accounts or third-party access (e.g., vendors). Codes expire after use or within a set timeframe (e.g., 10 minutes).

      - Trusted Device Lists
      Whitelist devices by fingerprint (hardware/software attributes) to bypass multi-factor authentication (MFA) for known, secure endpoints. Example: A corporate laptop with consistent biometric and network profiles may auto-approve logins.

      - Session Timeout Customization
      Adjust automatic session termination intervals (e.g., 15 minutes of inactivity) to mitigate session hijacking risks. Shorter timeouts are recommended for high-security accounts.

      - Emergency Access Freeze
      Temporarily lock all account access via a one-click toggle, useful during suspected breaches or when credentials are compromised. Requires re-authentication via a backup method (e.g., recovery phone).

      Integration with Third-Party Services and APIs in Master NetZero Message Center

      The Master NetZero Message Center supports seamless integration with third-party applications and APIs to enhance user experience, automate workflows, and enable secure data sharing. Through standardized API protocols, developers can connect budgeting tools, smart home systems, and energy management platforms to NetZero accounts while adhering to strict security and compliance requirements. This integration leverages OAuth 2.0 for authentication, ensuring granular control over permissions and data access. Below is a technical breakdown of the API architecture, authentication methods, and implementation best practices for third-party developers.
      

      API Architecture and Authentication Framework

      The Master NetZero Message Center employs a RESTful API with OAuth 2.0 as the primary authentication mechanism. This framework allows third-party applications to request limited or full access to user accounts based on predefined scopes. The API follows industry-standard practices for token management, session validation, and secure data transmission.

      Key components of the API architecture include:
      

      OAuth 2.0 Authorization Server: Validates client credentials and issues access tokens.

      Resource Server: Hosts protected endpoints requiring authentication (e.g., `/api/user/energy-usage`).

      Client Applications: Third-party tools (e.g., budgeting apps, IoT platforms) that request user consent for data access.

      Token Endpoints: `/oauth/token` for token issuance and `/oauth/revoke` for token revocation.

      The authentication flow begins with the client redirecting the user to NetZero’s OAuth authorization endpoint (`/oauth/authorize`), where the user grants or denies permissions. Upon approval, NetZero redirects the client with an authorization code, which is exchanged for an access token via the token endpoint. This token is included in subsequent API requests under the `Authorization: Bearer ` header.
      

      API Endpoints for Authentication and Session Management

      The following endpoints are critical for third-party integration, with request/response formats adhering to JSON standards. All endpoints require HTTPS for secure communication.

      #### 1. OAuth Authorization Endpoint
      Purpose: Initiates the OAuth flow by redirecting the user to NetZero for permission grants.
      Request URL:

      https://api.netzero.com/oauth/authorize?
      response_type=code&
      client_id={CLIENT_ID}&
      redirect_uri={ENCODED_REDIRECT_URI}&
      scope={SCOPE}&
      state={STATE}

      Required Parameters:
      

      `client_id`: Registered third-party application ID.

      `redirect_uri`: Pre-registered URI for OAuth callbacks (must match registration).

      `scope`: Space-separated list of requested permissions (e.g., `energy_data read write`).

      `state`: CSRF protection parameter (must be validated post-redirection).

      Response:
      Upon user approval, NetZero redirects to `redirect_uri` with:

      redirect_uri?code={AUTH_CODE}&state={STATE}

      #### 2. Token Exchange Endpoint
      Purpose: Exchanges an authorization code for an access token.

      OAuth Scopes and Permissions

      NetZero’s API uses granular scopes to define the level of access granted to third-party applications. Developers must request only the necessary permissions to minimize security risks. Common scopes include:
      

      Scope	Description
      `energy_data.read`	Access to historical and real-time energy consumption data.
      `energy_data.write`	Ability to modify energy-related settings (e.g., budget alerts).
      `billing.read`	View billing statements and payment history.
      `billing.write`	Initiate payments or update billing preferences.
      `smart_home.control`	Integrate with IoT devices (e.g., thermostats, solar panels) for automation.
      `profile.read`	Access user account details (name, email, account status).

      Example Request for Multiple Scopes:

      https://api.netzero.com/oauth/authorize?
      response_type=code&
      client_id=abc123xyz&
      redirect_uri=https://app.example.com/callback&
      scope=energy_data.read%20billing.read%20smart_home.control&
      state=xyz789
      

      Implementing Secure API Calls with Postman and cURL

      Developers can test API interactions using tools like Postman or cURL. Below are examples for common operations, including token acquisition and session validation.

      #### Example 1: Token Exchange via cURL

      curl -X POST "https://api.netzero.com/oauth/token" \
      -H "Content-Type: application/x-www-form-urlencoded" \
      -H "Authorization: Basic $(echo -n 'abc123xyz:secret123' | base64)" \
      -d "grant_type=authorization_code" \
      -d "code=AUTH_CODE_FROM_REDIRECT" \
      -d "redirect_uri=https://app.example.com/callback" \
      -d "client_id=abc123xyz" \
      -d "client_secret=secret123"

      #### Example 2: Fetching Energy Data with Postman
      1. Set Headers:
      

      `Authorization: Bearer {ACCESS_TOKEN}`

      `Accept: application/json`

      2. Send GET Request:

      GET https://api.netzero.com/api/user/energy-usage?start_date=2024-01-01&end_date=2024-01-31

      3. Expected Response:

      {
      "consumption": [
      {
      "date": "2024-01-01",
      "kwh": 15.2,
      "cost": 2.28
      }
      ],
      "metadata": {
      "unit": "kWh",
      "currency": "USD"
      }
      }

      #### Example 3: Refreshing a Token via cURL

      curl -X POST "https://api.netzero.com/oauth/token" \
      -H "Content-Type: application/x-www-form-urlencoded" \
      -H "Authorization: Basic $(echo -n 'abc123xyz:secret123' | base64)" \
      -d "grant_type=refresh_token" \
      -d "refresh_token=rt_123456789" \
      -d "client_id=abc123xyz" \
      -d "client_secret=secret123"
