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.
