Trouble shoot

Question

How do I update my authenticator phone number to verify my ownership of the account.

Answer 1

Hi! You need your account to be signed in on at least one device to change your phone number; otherwise, you'll need to recover your account.

Go to https://account.microsoft.com/account?lang=en-us > Click on Security (Shield icon) > Manage How I Sign In under Account Security.

If your email is linked to Outlook Mobile, click on the Profile icon > Gear icon > Accounts > Outlook > Account Security.

If you don't have access to your account on any of the devices, you'll need to recover it another way.

You can try using the Microsoft Sign-In Assistance Tool.

If you're unable to recover your Account, you'll need to use the Recovery forms. You can try these two forms:

https://support.microsoft.com/en-us/account-billing/guidance-notes-for-the-microsoft-account-recovery-form-4dd8fef1-33d2-4fbe-9352-66127ab9b50e

These are the methods Microsoft provides for account recovery. I have already used the recovery form, and I managed to recover my account after a few days.

• You can submit the form multiple times.
• Try to remember important personal information.
• Look for old emails that may have been sent to friends or family.
• Don't give up. The form works if you provide accurate information. If it didn't work like that, anyone could steal your account.
