Microsoft account

Question

Deleted house number and wanted to change to mobile number on my Microsoft account. Unable to do so.

Answer 1

Microsoft announced they are deprecating SMS recovery codes on Microsoft accounts, it is no longer possible to add a new Phone number to a Microsoft account, they indicate we should not use the Authenticator app, a PassKey or add a new Email address for account recovery.

Answer 2

I have difficulty with these things. 800 number available?

Answer 3

For a personal Microsoft account, adding a new phone number as a security verification method may no longer be available. In that case, only options such as a recovery email address, Microsoft Authenticator, or a passkey may appear under security settings.

If the goal is to change the phone number used to sign in:

1. Go to Manage how you sign in to Microsoft and sign in.
2. Under Account alias, check whether the old phone number is listed.
3. Select Remove next to the old number.
4. Select Add phone number and follow the prompts.

If the goal is to change the phone number used for security verification:

1. Open the Microsoft account Security tab.
2. Select Manage how I sign in.
3. Select Add a new way to sign in or verify.
4. If phone number is not offered, use one of the available methods instead:
   • recovery email address
   • Microsoft Authenticator
   • passkey

If the old phone number was removed and access is now blocked:

1. At the Verify your identity prompt, select I don't have any of these.
2. Follow the instructions to replace security info.
3. After replacing all security info, there is a 30-day wait before sign-in is restored.

If a mobile number is already linked to another Microsoft account:

• Select Transfer if that option appears.
• If Transfer does not appear, select Change number and use a different mobile number, or try again after 30 days.
• A phone number can only be added to a single Microsoft account.

Also note:

• VOIP numbers cannot be added for sign-in or verification codes.
• Avoid making repeated code requests, because that can temporarily block code delivery.
