How to Secure Your Microsoft Account After Unusual Sign-in Activity
Question details
The user received a notification from Microsoft regarding a suspicious or unusual account sign-in from an unfamiliar location or device.
- Product
- Microsoft Account
- Device & OS
- not provided
- Scenario
- Receiving a security alert email or notification about unauthorized access attempts.
- Observed behavior
- Microsoft reports an unusual sign-in, displaying an unfamiliar IP address, operating system, browser, and sign-in date.
Verify that the alert email is genuinely from Microsoft (sent from @accountprotection.microsoft.com) before clicking any links, as scammers often send fake security alerts.
Secure Your Account by Changing Password and Enabling 2FA
The most effective way to lock out unauthorized users is to immediately update your login credentials and add a second layer of security.
If you do not recognize the sign-in details provided in the alert, your account credentials may have been compromised. Taking immediate action is critical to prevent data loss or identity theft.
Navigate directly to the official Microsoft account security page (account.microsoft.com/security) using a trusted web browser.
Select 'Change my password'. Create a strong, unique password that you do not use on any other websites or services.
Click on 'Review recent activity' on the security dashboard to check for any other unauthorized access attempts and confirm your changes.
Go to 'Advanced security options' and follow the prompts to turn on two-step verification. This requires an extra security code when signing in from an untrusted device.

Frequently Asked Questions
How can I tell if a Microsoft unusual sign-in email is real?
Legitimate Microsoft security emails always come from the domain '@accountprotection.microsoft.com'. If the sender's email address is different, or if it asks for your password directly in the email, it is likely a phishing attempt.
What happens if I ignore an unusual sign-in alert?
Ignoring a genuine alert could allow hackers full access to your Microsoft account. This means they could read your Outlook emails, access files stored in OneDrive, or misuse any payment methods linked to your account.
Why did I get an unusual sign-in alert when I logged in myself?
You may trigger an alert yourself if you sign in from a new device, use a VPN, use a new browser, or travel to a different location. If you recognize the details (IP, time, and device), you can safely mark the activity as 'This was me' on the recent activity page.
