Windows 10: Will I be able to replace my Microsoft account phone number after 30 days with the same...

My Microsoft security info/phone number should be replace today but it hasn't been replace. For example, I change my security info at 3:30 pm, will it also be replace at time of 3:30 pm. And will I also get a notification saying it has been replaced?

Change account phone number

Hello SeanPR11,

I am Jaspreet Singh.

Please use the steps listed here and first remove all your security information. (this will take 30 days after which you will be able to add new phone number without being required a code first)

Follow the steps under the title "Remove Security information" on this link : https://support.microsoft.com/en-us/account-bil...

* There is no way to fast track this 30 day process.

 

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.

 

Suspended Account

Something similar happened to me. I set up a computer for a family member and when logging in on a secondary MS acct for support purposes, I incorrectly typed my password and was then asked to enter a code texted to a last 4 nos. that I didn't realize was a 2nd phone that I used for 2-step verification. So when I said that wasn't my backup number, the acct was auto-locked for 30 days, nothing to do but wait. At least the family member had a Local Account and was able to use the device until I was re-instated, whereupon I was able to sign-in and verify my 2nd step in the verification process.
If you used your land line as the 2nd step, I'm afraid, you're, likewise, locked out until the 30 day period is over. By then, either get a secondary email acct, as suggested, or a burner phone that takes texts so you're VERY clear as to what your 2nd verification option is. This is a case where having a Local Acct with admin privileges would be invaluable. Good Luck with your efforts.
