account info

For personal Microsoft accounts, a phone number may not appear in Account info because Microsoft no longer always offers phone numbers as a new sign-in or verification method.

Supported reasons include:

1. Phone numbers may no longer be available as a new security method In Security > Manage how I sign in, the option to add a new phone number might not be shown. Available methods may be recovery email, Microsoft Authenticator, or a passkey instead.
2. A phone number can only be linked to one Microsoft account If that number is already associated with another Microsoft account, it will not be added to the current account.
3. The number may be pending or recently changed If security info was removed and replaced, changes can take 30 days to take effect.

What to check:

1. Go to https://account.microsoft.com/security.
2. Select Manage how I sign in.
3. Check whether the account shows other verification methods instead of a phone number.
4. If the phone option is missing, use a recovery email, Microsoft Authenticator, or a passkey.
5. If the number is already used elsewhere, add a different mobile number instead.
