Production-ready authentication code — sign-in, password reset, OAuth, magic links, and session management — without rolling your own.
Authentication code is the highest-risk purchase in any marketplace. Verify the listing implements CSRF protection, rate limiting on login endpoints, and secure session management. JWT implementations should rotate refresh tokens. CodeCudos runs an automated security scan on every submission — listings with a high security grade have passed checks for common vulnerabilities including exposed secrets and insecure cookie flags.

Frequently asked questions
Should I buy an auth system or use NextAuth/Clerk?▾
Clerk and Auth.js (NextAuth) cover most needs out of the box. Buy a custom auth listing when you need full control over the data model, on-prem deployment, or a specific OAuth flow not supported by the SaaS options.
Are these auth systems audited?▾
CodeCudos runs an automated security scan, but no automated scan replaces a professional audit. For high-stakes deployments, treat the listing as a starting point and have it reviewed.
Do auth listings include 2FA / MFA?▾
The better listings do. Look for TOTP (Google Authenticator) support or WebAuthn passkeys. SMS-based 2FA is increasingly seen as legacy due to SIM-swap risk.
