The DELETE microsoftAuthenticatorAuthenticationMethod api has started returning a 403 error for some users.
The audit logs in the Entra admin centre are giving a status of clientError.
Users that are succeeding and failing have the same assigned roles in Entra and the API is being triggered from the same piece of code for everyone.

When you say "started returning a 403 error", does this mean that you had it working for the same users/apps before? Are you performing this via delegate or app permissions?
Just in case, you might want to retry with Privileged Authentication Administrator.
Yes, it was working until a few days ago. I'm using delegated permissions and I've tried with privileged authentication administrator and the issue still happens.
I did few quick tests on my end and I'm not able to replicate this. Given that it only seems to affect some users (and is not role/permission related), it might be best to open a support request and report this therein.
