MFA Accounts in Authenticator is lost after resetting phone

Hi,

I used to store various kinds of accounts in the Authenticator app to perform MFA (Multi Factor Authentication). But my phone broke last week, and had to be totally resetted to 0.

Alas, I have to reinstall my apps. When I reinstall Authenticator, all my registered accounts were gone, BUT my accounts still demanded the code generated in Authenticator.

Any way to solve this issue?

Regards

 

Can't reinstall Microsoft Authenticator after factory reset

I have a Lumia 950 XL and I recently had to do a factory reset on the phone to get it to work properly again. But now I can't reinstall the Authenticator app, leaving me locked out of multiple accounts I have set up with 2-step authentication, that is
a disaster!

The Store tells me I own the app, but I can't choose to install it, and it is not available anywhere in the app list of my phone.

 

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
