How to Remove a Security Key from Your Microsoft Account
Removing a security key from your Microsoft account stops unauthorized access. A security key is a small physical device or app that proves your identity when you sign in, acting like a digital key for your account.
Removing a security key from a Microsoft account is important if the physical key is lost, replaced, or no longer used. Microsoft accounts use security keys for protection beyond a simple password, offering a stronger security layer.
The steps to remove a security key are done through your Microsoft account settings. This process does not wipe any data stored on the physical security key itself.
Go to the Microsoft My Account page, sign in, and navigate to Security Info. Locate the security key you wish to remove and select the “Delete” option, then confirm your decision. This will prevent the key from accessing your account.
Steps to Remove a Security Key
Follow these steps carefully to remove a security key from your account.
Go to Your Microsoft Account Security Page
Open your web browser and head to the Microsoft My Account page. You may need to sign in with your work or school account details if you’re not already logged in.

Find Your Security Information
The Microsoft account security settings page displays proof of identity methods. Users will find their phone number, authenticator app, and security keys listed on this page.
Locate the Security Key to Remove
Microsoft account security settings list displays your security methods. Locate the specific security key for removal. Microsoft account security keys may have a user-assigned name or display "Security Key."
Select the “Delete” Option
Your Microsoft account security page lets you remove a security key you no longer need. Find the specific security key you want to delete and click the 'Delete' button right next to the security key. Double-check you have picked the correct security key, because once the security key is gone, you cannot use that security key to sign in.

Confirm Your Decision
Deleting your security key requires confirmation. The final confirmation message presents your last chance to stop the security key deletion process. To proceed with deleting the security key, click "OK" or "Confirm."
Check That It’s Removed
After you confirm, the security key should no longer appear in your list of security methods. You won’t be able to use that key to sign in to your account anymore. Your security info page will show the updated list.
