Exponential Backoff Lockout: Stopping Brute Force Without Leaking Account Existence

1. 1Implement silent failures for the first N login attempts
2. 2Configure exponential backoff with a cap at 15 minutes
3. 3Ensure status codes do not distinguish between locked and wrong credentials
4. 4Develop a proper reset mechanism for locked accounts
5. 5Test the exponential backoff lockout system for security and usability

Security engineers and developers on a team benefit from this knowledge to protect user accounts and prevent unauthorized access. It's essential for teams handling sensitive user data

💡 Silent failures and indistinguishable status codes are key to preventing account existence leaks

💡 Prevent brute force attacks without leaking account existence with exponential backoff lockout! #security #authentication
