To determine if the security alert you received is genuine, you can check the sender's email address. An email from Microsoft regarding account security should come from a domain ending in @accountprotection.microsoft.com, which matches the email address you provided. If this is the case, the alert is likely legitimate.
If you suspect that your account has been accessed without your knowledge, here are steps you should take to resolve the security issue:
- Change Your Password: Immediately change the password for the account associated with the email. Use a strong, unique password that you haven't used before.
- Enable Two-Factor Authentication: If you haven't already, enable two-factor authentication (2FA) for added security on your account.
- Review Account Activity: Check your account activity for any unauthorized actions. Look for unfamiliar logins or changes to your account settings.
- Secure Your Email: If you have other email accounts linked to this one, ensure they are secure as well.
- Contact Microsoft Support: If you still have concerns or if you find suspicious activity, contact Microsoft Support for further assistance.
Always be cautious and perform due diligence to verify the legitimacy of any security alerts you receive.
