Attempted unauthorised access attempt not showing up in 'recent activities'?

It’s understandable to feel concerned about unauthorized access attempts. When you receive a notification from Microsoft Authenticator for a sign-in attempt, it may not always appear in the recent sign-in activity for a few reasons:

1. Timing of Updates: There can be a delay in the system updating the recent activities. Sometimes, it takes time for unauthorized attempts to be reflected in the activity log.
2. Security Measures: If the sign-in attempt was blocked (as it should be since you denied it), it may not be logged as a successful attempt in the recent activities. Microsoft prioritizes security and may not log every denied attempt.
3. Location and Device Recognition: If the sign-in attempt was from a location or device that Microsoft recognizes as suspicious, it may trigger security protocols that prevent the attempt from being logged in your account's activity.

To enhance your account security:

• Ensure that your security information is up to date.
• Consider enabling additional security measures, such as two-factor authentication if not already enabled.
• Regularly review your account's security settings and recent activities.

If you continue to have concerns, it may be beneficial to contact Microsoft Support for further assistance.
