A Microsoft app for iOS and Android devices that enables authentication with two-factor verification, phone sign-in, and code generation
To review sign-in attempts and authentication requests, use the account activity views provided for Microsoft accounts or work/school accounts.
For a personal Microsoft account (Outlook.com, Hotmail, etc.):
- Go to the Recent activity page at https://account.live.com/Activity.
- Review the list of sign-ins from the last 30 days, including device and app details.
- If anything looks suspicious (unknown locations, devices, or multiple attempts), select Secure your account and follow the steps to change the password and update security info.
For a work or school account (Microsoft Entra ID):
- Go to the My Account portal at https://myaccount.microsoft.com/ and sign in.
- Select Recent activity from the left navigation.
- Expand each sign-in entry to see details such as location, app, browser, and operating system.
- If unfamiliar successful sign-ins are found, immediately change the password and then go to Security info (https://mysignins.microsoft.com/security-info) to update security methods.
If repeated sign-in attempts are blocking access to a work or school account, Microsoft Entra multifactor authentication may temporarily prevent additional attempts. In that case, either wait before trying again or use a different MFA method. If malicious activity is suspected, contact the organization’s IT administrator and ask them to review the Microsoft Entra sign-in logs.
For managed identities in Azure (if applicable):
- In the Azure portal, browse to Microsoft Entra ID.
- Under Monitoring, select Sign-in logs.
- Open the Managed identity sign-ins tab to view authentication attempts by managed identities.
If unrequested prompts appear on Outlook mobile or Authenticator, always select Deny unless the sign-in was initiated intentionally, then review recent activity as above and change the password if anything is unfamiliar.
