Change of Phone Number

If the number appears when Edge fills out web forms, edit it in Edge Autofill; if it is used to sign in or receive verification codes, update the Microsoft account instead.

Number saved in Edge Autofill

1. Open Microsoft Edge.
2. Select Settings and more (…) → Settings.
3. Go to Passwords and autofill → Addresses and more.
4. Locate the entry containing the old phone number.
5. Select its menu, then Edit and enter the new number—or delete the old entry and add a replacement.

Edge Autofill stores phone numbers as part of saved form information. You must be signed in to Edge to manage and sync that information.^1^

Number used to sign in to your Microsoft account

This is an account alias rather than an Edge setting:

1. Sign in to the Microsoft account associated with the Edge profile.
2. Open Your info → Manage how you sign in to Microsoft.
3. Select Add phone number, enter the new number, and complete verification.
4. After the new number works, select Remove beside the old number.

If the old number is the primary alias, another alias must be made primary before it can be removed.^2^

If Microsoft says the new number is already associated with another account:

• Select Transfer if that option appears.
• If Transfer is unavailable because the number was recently used on another account, select Change number and use a different number. For a newly acquired number, Microsoft advises trying again after 30 days.^3^

Number used for verification codes

For a personal Microsoft account:

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 a phone option is offered, enter the new number and verify the code before removing access to the old method.

The phone option may not be available. In that case, add a recovery email, Microsoft Authenticator, or a passkey instead.^4^

For a work or school account, manage the number on the organization’s Security info page. Add and test the replacement method before selecting Delete beside the old Phone entry.^5^
