Windows 10: How can I remove my account from Microsoft Authentication application when I lost my phone?

Hello! I lost my phone and it has the Microsoft Authentication Application. I am afraid if somebody finds it then he will be able to acces to my email. How can I remove the app or my account from the application when I am not having that phone and I want to set the Authentication on my new Phone?

How to remove lost phone's authenticator from work Microsoft account?

Recently lost my phone that has my Microsoft authenticator on it for my work account and I can't seem to find a way to remove it from the account. This is preventing me from signing in to Visual Studio.

Any way that I've found will prompt me for the authenticator code to access, which of course I can't do.

Please let me know.

 

Microsoft Account authentication

After more research, I have found my answer. It looks like the issue was that Microsoft released a new Microsoft Authenticator app with the features first introduced in Microsoft Authenticator Beta. The new app received a prompt to approve access to my Microsoft
Account when signing on from a new PC, though I find it strange that the beta app wasn't directly upgraded to the new version of the app.

Microsoft now has three 2 step authentication apps available in the store for Windows 10 Mobile:

• Authenticator - original app from Windows Phone 8
• Microsoft Authenticator Beta - originally released to Windows 10 users when Windows 10 Mobile was only available on the Windows Insider program.
• Microsoft Authenticator - the official Windows 10 app no longer in beta

 

New Microsoft Authenticator app version released for iOS - Aug. 30

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.
