A cloud-based identity and access management service for securing user authentication and resource access
Hi @Eleanor Delaney ,
This error: AADSTS50076: Due to a configuration change made by your administrator, or because you moved to a new location, you must use multi-factor authentication to access '00000003-0000-0000-c000-000000000000' indicates that your tenant now requires Multi-Factor Authentication (MFA) for the access scenario in use.
Since the resource in question ('00000003-0000-0000-c000-000000000000') is Microsoft Graph, it’s unlikely that you’re using the ROPC flow.
Recommended Actions:
Examine Sign-In Logs: To gain more insight into why this error is triggered, inspect the Azure AD sign-in logs. In particular, check the details associated with the correlation ID aaf737a1-23d2-42f7-9c03-cf1ec58dc57b to determine which Conditional Access policies were applied during the sign-in attempt.
Check Tenant Security Settings: Please review any recent changes to your tenant’s security policies in the Azure portal. Verify under Azure Active Directory > Security > Conditional Access as well as under Azure Active Directory > Properties > Manage Security Defaults if there are any policies enforcing MFA based on location, risk, or other factors.
