Yeah that’s true. I just have worries that the app might do something weird and require a log in and re-sync.

I have another 2FA app (Aegis) with the same keys added for my email and any other critical stuff.

The other option for traveling that might be better is use Keepass with the file stored on your phone, that way no internet is needed and there’s no chance of lockout from your password DB.

Convenience mostly, privacy needs to be convenient and easy for people, otherwise no one uses the tools.

Bluesky is a lot easier to use vs fediverse stuff, discovering stuff is also easier in my experience vs mastodon.
