Hello @Harris, David,
Thank you for connecting offline over the team's call.
As discussed, we observed that your users were being prompted for MFA registration each time they signed in to an application due to Self-Service Password Reset (SSPR) being enabled in your tenant. When SSPR is enabled, users must register at least one authentication method to complete the SSPR registration process.
Since you wanted to prevent users from being prompted for MFA registration, we have disabled SSPR in your tenant. After making this change, users were no longer prompted to register for MFA when signing in.
For more details on SSPR and its impact, you can refer to the official Microsoft documentation:
