1password along with seemingly every other mobile password manager slips up from time to time. Turn around time once something is disclosed is my main concern.
1Password didn't support Linux last time I checked. There are 3rd party libraries, but most of them don't support the newer keychain format. I still use it and just look up the password on my phone when I'm on a Linux system.
I've tried that library, actually. Last time I used it, it couldn't find some passwords in the vault, including (crucially) the one I use for SSO at work. It's totally possible I was just using it wrong – it would be nice if the repository had a demo command line tool or something.
