I have 1Password installed on my MacBook, and I'd like to quit the '1PasswordAgent' process (starts at ~login) that I see in the Activity Monitor, and which I wish to remove when playing a game, but the problem is that whenever I quit this process it just returns with a new PID a moment later.

Does anyone know of some way to remove this process?


Just remove the file ~/Library/LaunchAgents/ws.agile.1PasswordAgent.plist and reboot the machine.

(Maybe there's the same file in /Library/LaunchAgents/ws.agile.1PasswordAgent.plist)

EDIT : You can use Lingon (now discontinued, but the latest version still works) to check every startup services.


Open Terminal, then ask launchd to stop it:

$ launchctl unload ~/Library/LaunchAgents/ws.agile.1PasswordAgent.plist

That will immediately stop the 1Password agent, but won't prevent it from starting again on the next boot. If you want that, add -w to the command:

$ launchctl unload -w ~/Library/LaunchAgents/ws.agile.1PasswordAgent.plist

To re-enable it without rebooting, substitute load for unload in those commands.

If /Library/LaunchAgents/ws.agile.1PasswordAgent.plist also exists — as it does on my system — you might have to repeat those commands for that file, too.

Regarding Lingon (recommended in another answer) beware that the current version has moved to the Mac App Store, and as a result of the MAS sandboxing policies, it can no longer modify system-level services. Since the 1Password agent seems to install launchd entries at both the user and system level, it might work for this, and it might not.

    launchctl unload -w ~/Library/LaunchAgents/ws.agile.1PasswordAgent.plist would also disable it permanently. – Lri Oct 19 '12 at 15:32
  • Thanks, @LauriRanta. I've incorporated that into the answer. – Warren Young Oct 19 '12 at 16:05
  • 2019 update: 1Password's launchctl plist is not longer in that directory – Chris Nov 3 '19 at 3:10

Please refer to this article Completely Uninstalling 1Password

    You don't have to uninstall 1Password to get this to happen. – Warren Young Oct 18 '12 at 23:12

The method recommended by an AgileBits staff member in this thread is to: 1) Search for 1Password in the finder so you can open it. This will make the 1Password menu visible 1Password menu bar.

2) Click on the name "1Password" to open that menu. It will look like like this with the last option being "Quit 1Password". Don't click that yet.

2) Hold down the Control (^) and Option (⌥) keys. This will change the last option to "Quit 1Password Completely" Quit 1Password completely. Now select this option.


I made another user account and 1PasswordAgent does not run for that user, which I think is the best solution for my situation, because it will handle all similar situations with other programs.
