For me, I need authy, anki, and a couple of other apps or else I need a second phone. Luckily, anki is open source too and hopefully somebody ports the linux version for the smaller screen.

There is an Authy alternative ready for it.

There are also a ton of CLI tools to generate TOTP if thats what you're using authy for.
