Windows 10: How can I delete my old phone number and add my new number to my microsoft account?

How can I delete my old phone number and add my new number to my microsoft account?

Microsoft account and phone number linked

Microsoft account password recovery requires two verification codes being sent using two different verification methods. Each Microsoft account has at least two verification methods, the phone number and additional email address which are asked and required when you set up a new Microsoft account with a new hotmail.com or outlook.com email or using a third party email.

When the thief who got your phone tries to recover your password, all your verification methods / security info phone numbers and email addresses will be listed for him to select one. OK, the thief naturally selects your phone number, gets the code sent as a text message, and enters it.

But, clicking Next after entering the code he needs to select another security info contact (phone / email) from the list to receive second verification code.

Password recovery is not possible with just your phone, the system is clever enough to make it impossible by requiring two codes being sent to two different phones and / or emails.

You can add as many phone numbers and email address as you wish as security info contacts at https://account.live.com/proofs/mana...&refp=security. I wholeheartedly recommend that you add at least another security email address; if you only have one phone number and one email added, those which were required when you set up the Microsoft account, and that thief got your phone, the recovery would be as impossible to you as it is to him, you both having access to just one of required two verification methods.

To add a new email address or phone number as an alias:

1. Sign in to Manage how you sign in to Microsoft with your Microsoft account.

Sign in to your Microsoft account

2. You may be prompted to enter your Microsoft account password or to enter a code sent to the email address or phone number listed in your account's security information. By providing this info to us, we know the request is coming from you.

3. Under the Account aliases section, select either Add email or Add phone number.

4. If you selected Add a phone number, follow these steps:

5.Select your country from the list.

6. Enter the phone number you want to use, and then select Next.

7. When you add a new phone number, we'll send a text message to that number to verify it. Enter the code from the text message, and then select Next.

I hope that helps.
