1Password SSH support works on multiple platforms and allows you to import your own SSH keys. Secretive does not. (I have used Secretive and have an unsatisfactorily rejected issue about the way it hijacks all possible uses of the SSH agent. It’s disappointing, but I also understand it.)

I still hate the 1Password 8 UI and reject all of Dave Teare’s apologia for the UI garbage (if they either added multi-window or multi-tab support, then ~80% of my complaints would go away; if they eliminated the stupid Electron defaults for ⌘0 [mainly], ⌘-, and ⌘+ because resizing on the fly is something I never want to do with a password manager another ~10% of my complaints would go away; the rest won’t go away until they remember that Electron pseudo-modals are complete garbage and they need to DIAF).

I mostly interact with 1Password via the CLI and the browser extensions, since most of my passwords are already where they should be as I’ve been using 1Password since ~2006 (when it was 1Passwd and they were writing on the Switcher’s Blog).
