When implementing authentication systems, follow these security-focused guidelines to protect user data and ensure robust access control:

1. Use Strong Cryptographic Protocols 🔐

  • Always enable HTTPS to encrypt data in transit.
  • Implement OAuth 2.0 for third-party access (see OAuth 2.0 Guide for details).
  • Hash passwords with bcrypt or Argon2 instead of raw storage.

2. Token Management Tips 🎟️

  • Issue short-lived tokens (e.g., 15-minute JWTs) and refresh them securely.
  • Avoid exposing sensitive data in tokens (e.g., user passwords).
  • Validate tokens on every request to prevent replay attacks.

3. Multi-Factor Authentication (MFA) ⚙️

  • Require MFA for critical actions like password changes or account access.
  • Support TOTP via authenticator apps (e.g., Google Authenticator).
  • Never store user secrets in client-side code or logs.

4. Session Security 📦

  • Use secure session cookies with HttpOnly and Secure flags.
  • Implement CSRF protection via tokens or SameSite attributes.
  • Rotate session IDs upon login or sensitive operations.
