Android app: export configuration as a password-protected zip file

[Douglas Silva]

An update: it seems that Seedvault can already backup this app's data, because it pretends to do a device-to-device transfer. [1]

That's good enough for those running the likes of LineageOS, but I still think the password-protected zip would still be useful in case you don't like to use Auto Backup.

It's the default on systems like LineageOS or CalyxOS. Seedvault does encrypted backups to any location; even offline, to a flash stick. Aegis Authenticator uses it, as long as the backup is advertised as encrypted. See [1], [2] and [3] and [4].

The messaging app Signal does something like this to export your messages (encrypted) and keep the last five versions of it.
