Its good, that simple.

Mega, Ich liebe es.

It does the job and it does it well enough.

I would like the ability to unlock the extention with Touch ID instead of a PIN, just like the desktop app. The Bitwarden extension supports it, so it is feasible.

I was using Apple passwords, but I use a bunch of machines Windows and Linux also so I needed something that would work across all of those.

Proton fits the bill. Works on all the desktop OSs that I use along with the various iOS and Android devices I have.
