Replit auth

Remember-Me Token Security Issue on Replit

Remember-me tokens are exposed in logs or storage. Session tokens compromise account security if leaked.

Persistent authentication tokens require secure storage and rotation.

Common Causes

  1. Tokens stored in plain text or weak hash
  2. Tokens logged in debug output
  3. Token expiration too long (years instead of days)
  4. No token rotation on sensitive operations
  5. Same token across multiple devices

How to Fix It

For Spring Security, use JDBC persistent remember-me tokens with unique device IDs. Hash tokens with bcrypt. Set expiration to 2-4 weeks max. Invalidate token on logout and password change. Don't log token values. Use rotating tokens: issue new token on each use, invalidate old ones.
