Currently, Microsoft Entra ID provides an Authentication Methods Activity dashboard that allows administrators to monitor authentication method registration and usage across their organization. This dashboard can help you track which authentication methods, including YubiKey, users are registered for and how they are being used.
To access this information:
- Sign in to the Microsoft Entra admin center as an administrator.
- Navigate to Entra ID > Authentication methods > Activity.
- You can view two tabs in the report: Registration and Usage. The Registration tab shows the number of users capable of using various authentication methods, while the Usage tab shows which methods were used for sign-in.
This should provide you with a consolidated view of user authentication methods, including YubiKey, without needing to check each user individually.
