Hi,

Thank you for writing to Microsoft Community Forums.

I understand that you want to how the Microsoft Authenticator App works.

The Microsoft Authenticator app helps you sign-in to your accounts if you use two-factor verification. Two-factor verification helps you to access your accounts more securely, especially while viewing
sensitive information. Because passwords can be forgotten, stolen, or compromised, two-factor verification is an additional security step that helps protect your account by making it harder for other people to break in.

You can use the Microsoft Authenticator app in multiple ways, including:

• Respond to a prompt for authentication after you sign in with your username and password.
  
• Sign-in without entering a password, using your username, the authenticator app, and your mobile device with your fingerprint, face, or PIN.
  
• As a code generator for any other accounts that support authenticator apps.
  

I suggest you refer to the article for more information on
What is the Microsoft Authenticator app?and you may also
refer to the article about Microsoft Authenticator app FAQ

However, let me point you in the right direction where you can get the appropriate assistance regarding this issue. I suggest you to post your query in
Microsoft Authenticator App forums
where we have expertise and support professionals.

Hope it helps.

Regards,

Hello,

I'm came from chatting with a technical support on Microsoft, with not result about,.. What happen if you change your phone number using the Microsoft Authenticator App? Well, I know there is a lot of people with the same issue, with the two step verification.
The problem is, when you change your phone and change the number, you can't enter to your privacy & security option, because resend you to the two step verification and show you to put the code that they resend to your Microsoft Authenticator App, that was
on your other phone, with the old number and you can't get that code to enter or to update your information.

You can enter to all your account via web or mobile, but you can't update the old phone in your account info, to fix the problem on the App Microsoft Authenticator in the new phone or via Web.

If someone can resolve that, I appreciate the solution, because I can't resolve with the Microsoft support to gain access to my information and update it.

 

New Microsoft Authenticator version for Android and iOS - Oct. 12

Two factor authentication (TFA) is easy, convenient, and secure when you use Microsoft Authenticator. Use your phone, not your password, to log into your Microsoft account. Just enter your username, then approve the notification sent to your phone. Your fingerprint, face ID, or PIN will provide a second layer of security in this two step verification process. After youve signed in with two factor authentication (TFA), youll have access to all your Microsoft products and services, such as Outlook, OneDrive, Office, and more.
