I use Microsoft Authenticator because it backs up my 2FA accounts to my iCloud and I believe to Microsoft's servers on Android. If you lose those you're in trouble. I'm sure there are other options that support that now. When I moved everything that I could over, the open source options didn't support this. If I wasn't happy with the best open source solution, I wanted to use something from a large vendor that would be well supported. Any vendor not named Google at least, I have the least amount of trust in them among the 500 pound gorillas. If you want to get ahead of this and save your accounts I've been using MS Authenticator for years now and am very happy with it.
