What is nauth-toolkit Node.js auth library?

nauth-toolkit is an open-source library embedding full auth (email, social, MFA) directly in Node.js apps like NestJS/Express, using your Postgres/MySQL.

Is nauth-toolkit secure for production use?

It covers CSRF, token rotation, MFA — teams run it live. But self-hosted means you own security; audit the code yourself.

Does nauth-toolkit replace Auth0 or Cognito?

For cost and control, yes — if you handle ops. No per-user fees, full stack in one TS config.
