Autentikasi dan sesi for Auth.js

high5 checks

Authentication is the highest-value target on any site: credential stuffing, session fixation and CSRF all aim at the same door.

What Auth.js must have

  • Login forms post over HTTPS with a CSRF token
  • Rate limiting and lockout on failed attempts
  • MFA available for privileged accounts
  • Passwords screened against known breach corpora
  • No account enumeration through error messages

How to fix it

  1. 1Add per-account and per-IP throttling
  2. 2Enforce MFA for admins and screen passwords with a k-anonymity API

Auth.js context

Authentication library for Next.js and other frameworks (formerly NextAuth).

Set a strong AUTH_SECRET and verify callbacks; debug mode discloses tokens.
