Google Authenticator is the worst, last time I used it. Too often my 2FA codes would not remain after updates. And when it did remain, it would not transfer to new phones. iPhone has a built in 2FA code generator. HTTP://TOTP.app is a web app that stores 2FA codes. Awesome to use. But you have to remember to download and back up the codes stored in TOTP. Microsoft Authenticator used to be my favorite because it would sync phenomenally well. In the following order, I would rank the 2FA code generators: 1. iPhone (especially if you are using iCloud password manager). 2. totp.app (you can use it even on desktops and every device you possibly have) 3. Microsoft auth (it only backs up to iCloud on iPhone. On android it backs up to an MS account. Can’t be used on desktop). Depending on the service, you have locked yourself out of that service. I screenshot and store 2FA codes on paper because too often I lost my codes because of Terrible unreliable apps.
