Is it possible to change 2FA app? (Google authenticator is not safe)

[Linux]

Google Authenticator has been marked as a security risk for syncing data in plain text without encryption.

Is there a way, that we use another app, because it's mandatory in here at the moment?

Google Authenticator uses the TOTP standard which is supported by any number of apps.  If you go to a website that has Google Authenticator support for 2FA, you can scan the QR code or or type the secret key into (insert your favorite 2FA app here) and it will work just fine.

 

Microsoft Authenticator is an option.  It supports the same type of codes.  I'm sure there are zillions more options for phone apps.  Myself, I hate having this tied to my phone.  I use KeePassXC as a password manager on my desktop.  It supports also TOTP codes so I just file them in there.  I can access them on my phone with the app "KeePassium" which supports the same database format and TOTP codes as well.

 

This is for setting up a new 2FA entry from scratch.  As for migrating existing codes off of Google Authenticator and onto a different app, I have no idea...  I haven't used Google Authenticator in many years so I'm not sure what import/export functionality it has.

If you're migrating from GAuth to MSAuth I'd suggest going with Aegis or Ente. Its better to export new ones to Cloud or local backup. MS Auth doesn't even export existing 2FA codes unlike GAuth. Unlike their marketing for MS Auth iOS and Android are not cross compatible since iOS uses iCloud so you can't sync from Outlook account in Android.
