What should I do against a lot of fake sign in request

Question

I've been getting multiple authentication requests on the Authenticator app on my mobile since last week, but I really dont know, who is trying to log into my account! Is there anything I should do?

Answer 1

If you are receiving multiple authentication requests on your Microsoft Authenticator app, it may indicate that someone is attempting to access your account. Here are some steps you can take to protect your account:

1. Do Not Approve Unrecognized Requests: If you do not recognize the sign-in attempts, do not approve them. Instead, deny the requests.
2. Change Your Password: Immediately change your password to something strong and unique. Ensure that it is not similar to any previous passwords you have used.
3. Enable Multi-Factor Authentication (MFA): If you haven't already, ensure that MFA is enabled for your account. This adds an extra layer of security.
4. Check for Account Compromise: Review your account activity for any unauthorized access or changes. If you see anything suspicious, report it to your organization’s IT department or Microsoft support.
5. Use Security Features: Utilize any security features available to you, such as alerts for unusual sign-in activities or notifications for changes to your account settings.
6. Contact Support: If the problem persists, consider reaching out to Microsoft support for assistance. They can help you secure your account and investigate the sign-in attempts.

Taking these steps can help mitigate the risk of unauthorized access to your account.
