A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
You can check the Microsoft Entra sign-in logs to monitor authentication events, including multifactor authentication (MFA) requests. While these logs primarily display successful authentications, they also contain information about denied requests. However, there is no dedicated feature in the Microsoft Authenticator app to view a comprehensive history of all unsuccessful or denied authentications.
To access the sign-in logs:
- Log in to the Microsoft Entra admin center.
- Go to Entra ID > Users.
- Click on Sign-in logs to see a list of sign-in events along with their statuses.
- You can select individual events to view more details, including any reasons for denial that may be provided.
If you are receiving notifications for logins that you did not initiate, it is important to secure your account further by changing your password again and reviewing any connected applications or permissions to ensure your account's safety.
