Authentication Failure

🎯 Purpose

Handles various authentication failure scenarios, implements security measures like account lockouts, and provides user guidance for recovery from authentication errors.


🚨 Authentication Failure Types

🔒 Incorrect Credentials

  • Scenario: User provides wrong Password, Email OTP, or SMS Authentication Code
  • System Response: Authentication error displayed to user
  • Attempt Tracking: System decrements available attempts counter
  • User Impact: Opportunity to retry with correct credentials

📊 Attempt Counter System

  • Configuration: Attempt limits are configurable (e.g., 5 attempts for password)
  • Tracking: Separate counters for different authentication factors
  • Exhaustion: All attempts exhausted triggers account lockout

🔐 Account Lockout Process

  • Trigger: User exhausts all available authentication attempts
  • Duration: Account blocked for configurable cooling period
  • User Experience: Clear error message indicating lockout status
  • Automatic Recovery: User automatically unblocked after cooling period expires
