Authentication
Implement secure authentication with OAuth, JWT, SSO, and multi-factor authentication.
How it works
Generates complete auth systems: JWT with rotation and refresh tokens, OAuth 2.0 (authorization code, PKCE), session management, and MFA. Handles password hashing (argon2), account lockout, email verification, and password reset. Follows OWASP guidelines.
Example prompts
“Build auth with email/password, OAuth, and MFA”
“Add refresh token rotation with reuse detection”
“Implement passwordless magic link authentication”
Real-world example
A SaaS built enterprise-grade auth: email/password with argon2, Google/GitHub OAuth via PKCE, TOTP MFA, refresh token rotation with family-based reuse detection, and SAML SSO — passing SOC 2 audit without findings.
