Steps To Reproduce

1. ​Delete one of the 2FA keys

Was that a local code in the authenticator app? Or was that a synced code in your authenticator app?

The local code

Is this caused by the Android built-in backup system? Because on my phone running with lineage OS do not have this problem.

Is this caused by the Android built-in backup system?

Did you wipe and restore your phone?

Actually, could you clarify on some other things?

Expected Result
All of the previously saved 2FA keys should have been removed

So, you expect all previously saved 2FA keys to have been removed? Also the not deleted ones or how do you mean that?

And your title is:

After reinstall the app existed 2FA keys still here

So, kind of "again": the 2FA keys that existed before the reinstall are the issue in general? Do you expect, after reinstall there should be no TOTP codes at all in the authenticator app? Please clarify the title.

I apologize for the confusion in my previous description. Let me clarify the situation in detail:

The Initial Discovery:
I originally had six 2FA keys stored locally in the Bitwarden Authenticator app. I uninstalled the app and then reinstalled it from the Google Play Store. To my surprise, all six 2FA keys were still there, even though the app had been removed.

The Persistent Data:
To fix this, I manually deleted each 2FA key one by one and cleared the app’s storage/cache. I then uninstalled the app and reinstalled it again from the Play Store. However, the same six 2FA keys reappeared once more.

Hm, @JerryIs-strong, honestly I wonder, if you would add a seventh TOTP code and didn't delete it, if that would be missing if you reinstalled. (in other words: if the "persistent data" of your authenticator app would be stuck now at the six TOTP codes, regardless of removing or adding other TOTP codes) 🤔

Hi~ @pamperer562580892423 I’ve just carried out a test, and as you might have expected, the seventh TOTP code has been lost, but the other six TOTP codes are still there.
