Signed up but cannot log in: signup vs login event types

TL;DR: Symptom: user created an account minutes ago and login fails. Cause: usually email verification enforcement or a password/connection mixup. Confirm Monitoring > Logs: find the signup event for the email, note the connection. Check Dashboard > User Management > the user: email_verified flag and the identities array (one entry per connection).

The fix

1. Email verification required before first login.
2. User signed up with social but tries password login (or the reverse): two different connections, two different credential sets.
3. Password manager saved a typo'd password at signup.
4. Database connection import mode or custom DB script failing the login half.
5. Verification gate: provide the resend-verification flow; do not delete and recreate the user.
6. Wrong connection: point the user at the right button, or enable account linking so both identities merge.
7. Typo'd password value password reset flow.
