Windows 10: Recovery methods saved - unexplained phone number

I've just updated my recovery methods to include my phone number. After adding the phone number, I received a popup confirming that my recovery methods are now saved - with an unexplained addition I'm unable to attach an image, apparently this is a known Microsoft issue and it's going to make this really annoying. The phone number that is showing 18708689557 I have never seen before. It certainly isn't mine. And it doesn't appear in my profile. For clarity, the phone number I added is also there; there are 2 phone numbers listed as recovery phone numbers, but only on the popup. Where did t

Trouble saving voicemail number

To access my voicemail it is my phone number, a pause and 4 digit pin.



I did the following steps:

• Turned off default voicemail number
• Added a , (for pause) at end of my phone number
• Added the 4 digit pin

I get the following error message We're having trouble saving your voicemail number right now. Try again later.



Any suggestions on how to correct this?

 

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.

 

save number to new contact

Using win10, tapping the icon or the number dials the number. Pressing and holding brings up a dropdown list that does not include save. Pls, any new suggestions?
