9 months ago, Raivo OTP for iOS was sold to Mobime. Raivo was hailed highly in terms of privacy, but was dethroned to 2FAS Auth after that incident. Today, Raivo launched an update, and after updating all of my entries were completely wiped. I didn’t have a backup, but even if I did you now have to pay in order to import/export TOTP codes. No thank you.
If you haven’t already, create a backup right now for all of your 2FA apps, even if you think it won’t break.
I’m all for open apps but you’d have the same problem on Android without root if the app chooses to keep its stuff in its private storage. It’s worth noting it’s not restricted to iOS.
You really don’t. Android has F-droid which has lots of 2FA apps. These apps are community built so it is unlikely that you would have the same issue. However, you can still backup most of them just in case
