  1. You may be asked to verify that you are the account owner by receiving a security code via text or email and then entering it online.
  2. You must have at least one phone number or email address set up to use for security. If you only have one, add and verify another now.
  3. Select Remove next to the phone number or email address that you want to remove.

You'll also receive a notification at your existing email address or phone number. This is a precaution in case someone else made the change. If that happens, you can cancel the change by following the instructions you receive with your notification.

Remove all of your security information

If you need to delete all of the phone numbers and email addresses that you’ve previously set up (for example, if you can no longer access them), see Update all of your Microsoft account security information.
