What is the best way to add authentication to an app?

Use a managed provider. Session handling, token refresh, and account recovery are where hand-rolled auth breaks, and an agent writing it from scratch will produce something that works and is quietly unsafe.

What to look for

  • 01Does it hand you a verified session server-side, or only a client-side token you must validate yourself?
  • 02Does it cover recovery, email change, and session revocation? Those are most of the real work.
  • 03Does authorization integrate with your database's access rules, or sit beside them?

Common questions

Should I let an AI agent write authentication from scratch?
No. It will produce something that logs users in and is subtly wrong — token validation on the client only, sessions that never revoke, redirects that can be pointed anywhere. Use a provider.
What is the most common auth bug in generated code?
Trusting a client-supplied user ID instead of the server-verified session, which lets any authenticated user act as any other by changing one value in the request.
