How to change phone number with microsoft 365 account on a mac?

Answer 1

Hello

Do you mean the phone number that receives the verification code?

If so, for personal Microsoft accounts, Microsoft now says you can no longer add a phone number as a new security method. Their current support article states: “For increased security, you can no longer add a phone number” when adding a new way to verify sign-in. https://support.microsoft.com/en-us/account-billing/microsoft-account-security-info-verification-codes-bf2505ca-cae5-c5b4-77d1-69d3343a5452

If you can still access your account, go to https://account.live.com > Security > Manage how I sign in, Add it there, and use the options offered you there to add a new verification method.

If you cannot access your account due to the code being sent to an old phone number, look for an option like “Show more verification methods” to see if you have a backup (e.g., a phone number or alternate email).

If you don’t have access to any of the options listed, select “I don’t have any of these.” This will begin the recovery process. As part of that process, Microsoft will let you add new contact information — but only after a 30-day waiting period.

This 30-day delay is intentional. It’s a security safeguard designed to protect users in case someone else tries to hijack their account by changing recovery info. The wait gives the rightful owner time to notice and stop unauthorized changes.

Unfortunately, this policy cannot be bypassed. You can read more about it directly from Microsoft here:

The Q&A Assist AI bot almost got it correct...

On your Account page you first need to click the Edit Account Info link in the upper right corner of the Account Info section.

You then can enter the new phone number & remove the orignal.

To change the phone number associated with a personal Microsoft 365 (Microsoft account) on macOS, update the phone number in the Microsoft account security/alias settings. This is done in a browser and works the same on Mac and Windows.

Follow these steps:

1. Open a browser on the Mac and go to the Microsoft account “Your info” / sign-in management page: https://account.live.com/names/manage.
2. Sign in with the Microsoft 365 account.
3. Under the account info, choose one of:
   • Add phone number to add a new number, or
   • Remove next to an existing number to delete it.
4. Follow the prompts to verify the new phone number (a code may be sent by SMS).

If the phone number is used as an alias or sign-in method and needs to be changed or removed, the same page is used to manage aliases (email addresses and phone numbers). Phone numbers and email addresses here are aliases that share the same account data and password.

If the phone number is already in use on another Microsoft account and an error appears such as “phone number is already used,” follow the on-screen options like Transfer number or Change number as described in the help article.

For Skype-specific phone number changes tied to the Microsoft account, use the “Manage how you sign in to Microsoft” page, remove the existing phone number under Account alias, and then add a different phone number.
