Frequently Asked Questions

Should I use personal-account or work-account recovery?

A personal Microsoft account uses the Microsoft password reset or recovery form. A work or school account uses organization self-service reset or an administrator.

When should I remove an old authentication method?

Only after a new method has been registered and tested. Removing the last working method can lock the account out.

Can Microsoft support bypass ownership verification?

No. Recovery requires verified security information, a recovery form, or authorized tenant administration.

How can I confirm that signing in to Microsoft 365 when authenticator is not working was successful?
