TimeBack SSO System

Single Sign-On authentication system for Alpha School applications

TimeBack SSO Overview

TimeBack’s Single Sign-On (SSO) system provides seamless authentication across all Alpha School applications and services. Built specifically for educational environments, it ensures students, educators, and administrators can access all necessary tools without multiple login prompts.

Why SSO Matters for Alpha School

Seamless Educational Experience

• No Learning Interruptions: Students stay focused on learning rather than managing credentials
• Instant Access: Quick transitions between educational tools and platforms
• Reduced Cognitive Load: Eliminates password fatigue and login friction

Enhanced Security

• Centralized Authentication: Single point of security control and monitoring
• Device Fingerprinting: Advanced security through unique device identification
• Session Management: Intelligent session handling across multiple domains

Administrative Efficiency

• Simplified User Management: Single identity source for all Alpha School services
• Audit Trail: Comprehensive logging of authentication events
• Reduced Support Burden: Fewer password reset requests and login issues

How TimeBack SSO Works

Device Fingerprinting Technology

TimeBack SSO uses advanced device fingerprinting to create unique identifiers for each device without requiring cookies or shared storage:

// Device fingerprint components
const fingerprint = {
  userAgent: navigator.userAgent,
  language: navigator.language,
  screenResolution: `${screen.width}x${screen.height}`,
  colorDepth: screen.colorDepth,
  timezone: new Date().getTimezoneOffset(),
  hardwareConcurrency: navigator.hardwareConcurrency,
  canvasFingerprint: generateCanvasFingerprint()
}

Cross-Domain Authentication Flow

1. Initial Login

   User authenticates on any Alpha School domain (e.g., student.alpha.school)

2. Session Registration

   Device fingerprint and domain are registered with TimeBack’s authentication service

3. Cross-Domain Access

   When accessing another domain (e.g., tutoring.alpha.school), the system checks for existing sessions

4. Automatic Authentication

   If a valid session exists, a new JWT token is issued automatically

Session Management

TimeBack SSO maintains intelligent session management:

• Active Session Tracking: Real-time monitoring of user sessions across domains
• Device-Based Security: Each device maintains its own authentication state
• Graceful Expiration: Automatic token refresh and session extension
• Selective Logout: Option to logout from current device or all devices
