Review Activity and Change Your Account Password

Immediately updating your password and reviewing active sessions is the best way to block unauthorized access and reset stuck device connections.

If someone else is trying to access your account, or if an old app is stuck in an authentication loop, changing your password acts as an immediate reset. This invalidates old sessions and prevents further unauthorized login attempts.

1
Review Recent Activity

Log in to your Microsoft account security page and navigate to the 'Recent activity' section. Look for unfamiliar locations, IP addresses, or unrecognized devices that trigger the 'Additional Verification Requested' prompt.

2
Change Your Password

Go to the 'Password security' section, select 'Change my password', and create a strong, unique password that you haven't used before.

3
Sign Out Everywhere

Under 'Advanced security options', scroll down and select the 'Sign me out' option to terminate all unrecognized or active sessions across all devices.

Review Activity and Change Your Account Password
Device Re-authentication: Changing your password will require you to sign back in on all your personal devices, including smartphones, tablets, and email applications.

Frequently Asked Questions

Why do I keep getting Microsoft account verification codes I didn't request?

This usually happens when someone is trying to log into your account and your security settings trigger a verification prompt to block them. It can also occur if a forgotten device or outdated email app is repeatedly trying to sync.

Can a third-party email app trigger the 'Additional Verification Requested' alert?

Yes. If an old email client or application is using outdated authentication methods, Microsoft may flag the connection attempt as suspicious and request additional verification to ensure your account remains secure.

Does changing my password stop unauthorized verification requests?

Yes, in most cases. Changing your password blocks anyone who has your old password from reaching the stage where a verification code is triggered, effectively stopping the unauthorized prompts.

How do I check which devices are connected to my Microsoft account?

You can view connected devices by logging into your Microsoft account dashboard, navigating to the 'Devices' section, and reviewing the list. You should immediately remove any devices you do not recognize.
