Invalid email or password
Password login failed with Invalid email or password. (AUTH_INVALID_CREDENTIALS). The product uses one generic message for unknown users and wrong passwords (no account enumeration).
Why this happens
Email/username not found, password mismatch, or related login gate returning the same generic code. Not a CSRF or captcha failure (those have their own messages).
Diagnose and fix
1. Confirm email/username and password; watch caps lock.
2. Use forgot password if needed (Login and password reset).
3. If the account is banned/inactive, other messages may appear after a successful credential check — try the exact address on file.
4. Social accounts without a password should use the provider button or set a password first.
