You have to import your GPG key to it and set up your git connection to your server and you're all set.
It also supports OTP generation which is really nice.

I use it and it works quite well.
Also gopass exists, which is useful to share secrets with teams + your personals, same interface. I wrote about it [0] + a cheatsheet [1]
If so, then a browser plugin would seem to provide better security. So this might be a little too KISS.
Does anyone have comments on how much of a concern it really is to have passwords travel by the clipboard?
As with many security matters, it will vary depending upon your threat model.
I generally feel that if you have something installed watching your clipboard for nefarious reasons then you've already got a bigger problem, and I prefer that potential security issue over having all my credentials integrated into the browser via a plugin (a clipboard sniffer will catch one or two things passing by, a hacked browser with integrated or add-in based password store might reveal everything at once).
If you use the clipboard for transfer, take the precaution of always clearing it soon after use. KeePass does this by default, as do some other similar tools.
Why is that? I trust my phone more than any other device because of it's encryption / secure enclaves / sandboxing etc.
It's just a bash script that used gpg and git. I find it the most KISS solution. Not available on phones but I don't trust my phone with my secrets anyway.
