Thank you for your post!
From your issue and follow-up, I understand that you were testing the Graph API and updated your user, and now you aren't able to login your Azure AD tenant / Azure Portal.
Since this is a locked-out scenario and you aren't able to login, I'd recommend reaching out to our Global Customer Service team, or you can contact the Azure Data Protection team for further assistance - (866-807-5850).
For future reference, I'd also recommend creating and managing an emergency access account in Azure AD. This account will help prevent being accidentally locked out of your Azure Active Directory (Azure AD) teannt because you can't sign in for any reason.
I hope this helps!
If you have any other questions, please let me know. Thank you for your time and patience throughout this issue.
