I use 1Password via the CLI (https://support.1password.com/command-line/) on Linux (well -- FreeBSD) Desktop all the time. I wrote a wrapper for the CLI (https://github.com/dcreemer/1pass) to make it a bit more ergonomic to use with things like FZF.

I used to use "pass" like others here, but did not like the Android experience.

*edited to add: and we use the 1Password team account at my day job -- and are satisfied customers. I'm sure other products work well too -- just my one data point.
