What it means

The login service couldn't match that email and password. Besides a typo, it often means the account was created with Google/magic link (no password), or in a different project.

How to fix it: paste this prompt into your AI builder

Fix prompt for Lovable, Bolt, Cursor, Replit, v0, Windsurf
Users get "Invalid login credentials". Verify the app connects to the correct Supabase/Firebase project, that email/password sign-in is enabled, and that the email is trimmed and lowercased before submission. Add a clear message and a 'forgot password' flow, and detect accounts that signed up with another provider. Don't change unrelated code.

If the AI can't fix it: manual steps

  1. Check in Supabase Authentication, Users whether the user exists and which provider they used.
