Verification

This is a potential sign that someone is attempting to access your Microsoft account. It does not necessarily mean your account has been compromised, but you should treat the situation seriously.

Someone may have your email address and password and be attempting to complete the sign-in process. Alternatively, someone may be entering your phone number or email address by mistake. If you are receiving repeated codes, it could also be an attempt to overwhelm you into approving a fraudulent sign-in.

Do not approve any sign-in requests you did not initiate. Do not share the verification codes with anyone, even if they claim to be Microsoft Support.

To stop the attempts and secure your account, take the following steps.

First, change your Microsoft account password. Go to https://account.microsoft.com/security and select the option to change your password. Use a strong, unique password that you do not use for any other account. If you are receiving codes for a work or school account, contact your organization's IT administrator instead.

Next, review your sign-in activity. Visit https://account.live.com/Activity and examine recent sign-ins. Look for unfamiliar locations, devices, successful sign-ins, or unusual activity. Microsoft may show unsuccessful attempts as well. If you see an unfamiliar successful sign-in, select the option to report it as unauthorized.

Then, sign out of all sessions. From your Microsoft account security settings, use the option to sign out everywhere, if available. This can help terminate existing sessions, although it may take some time to take effect.

You should also review your authentication methods at https://account.microsoft.com/security. Remove any unfamiliar phone numbers, email addresses, or authentication methods. Consider using Microsoft Authenticator passwordless sign-in or a passkey to strengthen account security.

Finally, if you are receiving SMS verification codes, changing your password and reviewing your security settings should help stop someone who is trying to sign in using your old credentials. If the codes continue, review your sign-in activity again.
