AADSTS50056
Invalid or null password
What it means
No password exists in the directory for this user.
How to fix it
Common with federated or passwordless-only accounts. Check the authentication method the app is trying to use.
How to investigate
- Confirm which account the user actually signed in with. A personal account or the wrong tenant causes many of these.
- Check the user object: enabled, licensed, in the right tenant, and with no recent password change or reset.
- Look at the sign-in logs over a few days for a pattern, such as repeated failures from one IP address.
- Search the sign-in logs for the request ID or correlation ID from the troubleshooting details on the error page.
