Password Recovery and Reset Mechanisms

Password Recovery and Reset Mechanisms

Password recovery mechanisms often become the weakest link in otherwise secure authentication systems. Security questions provide poor security, with answers often discoverable through social media or public records. Email-based reset links offer better security but require proper implementation to prevent exploitation.

Secure password reset requires multiple defensive layers. Time-limited tokens prevent long-term vulnerability from intercepted reset emails. Single-use tokens prevent replay attacks. Cryptographically secure token generation ensures unpredictability. Rate limiting on reset requests prevents abuse, while notification emails for password changes alert users to unauthorized access.
