| Feature | Impact on Password Recovery | |--------|-----------------------------| | for stored credentials | Brute-force is slower; requires GPU acceleration | | Argon2id hashing (default) | Resists rainbow table attacks; memory-hard function | | Delayed authentication (5-second pause after 3 failures) | Prevents rapid online guessing | | Recovery token integration | Allows self-service reset if enabled during setup | We will cover everything from built-in reset mechanisms
