A cloud-based identity and access management service for securing user authentication and resource access
Thank you for posting this in Microsoft Q&A.
I wanted to check if you are getting this error in Dev ops which is in Microsoft tenant? If this is happening in Microsoft tenant then you will have to contact internal MSIT team to fix this issue.
You can contact them by submitting your request in "http://aka.ms/itweb/filloutaform" This will be handled by internal Microsoft team (MSIT).
However, this issue can be fixed by revoking your user account MFA sessions. This can only be done by global admin of your tenant.
Let me know if you have any further questions.
