I always knew 1Password could export a login by dragging it to the desktop. However it took reader James W. to make the connection for me that I could put that link places other than the desktop, like in an OmniFocus note. To do so just click and drag.
This is really powerful. For instance, you could create a task with a list of sites you routinely change passwords on and set it out six months. When “the day” finally arrives, you can then get to all the logins from the OmniFocus note. It also works in OmniOutliner. Clever.
