Entra External Authentication Method giving AADSTS900144 missing externalAuthenticationMethodId

Hi All,

Has anyone else noticed in the last couple of days if EAM (External Authentication Method) is configured for MFA end users are getting:

AADSTS900144: The request body must contain the following parameter: 'externalAuthenticationMethodId'


Its been working for us fine for months/years but the last couple of days we are seeing heaps of the error above.


I have raised a support case but zero response so far


Regards,

Daniel

    So apparently MS applied a fix. We raised a ticket and with the help of Cisco (via DUO) got some traction. I'm not longer able to reproduce it.

    Yes, we are experiencing the same issue.  I had seen where the Entra Authentication Methods migration might be incomplete in another forum and I completed that, but we are still experiencing the same issue.
