B10. Need login

What this page helps you do​

Route quickly to the security and app path guidance that matters when users sign in.

Why it matters​

Login changes your launch risk immediately.

You should already have​

  • user accounts, sessions, or auth plans

Skip this page if​

  • the app has no user accounts

What to do​

Use a trusted auth library or provider, not a rushed custom system.

Common mistakes​

  • underestimating password reset and session handling
  • not separating admin access

Next step​

Go to C1. Login basics.

Advanced notes​

TODO for contributors: add a beginner-friendly login checklist with recovery flow questions.
