I definitely want to keep 2fa secrets on a phone, not my laptop, otherwise it's not a true second factor. If you have an Android build to try, I'll check it out. Also, part of my ideal requirements is an app built by an entity that I trust as much as Google. Open source is great, and this app is simple enough that I can skim the code once, but I'm not going to do it for every update, and I might miss something. There's still something to be said for that kind of accumulated trust. (I might not trust Google as much as I used to, but I still keep my life on gmail, so I have to trust them pretty far.)
