> coworker would have also worked

I think some consideration of the social aspect here is required. I agree that part of a marriage is agreeing to help one another in these small accountabilities, but, if a random coworker tried to impose this on me, I would not appreciate even the small imposition on my time. It's not, and shouldn't be, my job to help a random coworker stop procrastinating.

… But maybe you meant "a coworker who is also a friend", in which case it's fine; but still then I'd argue that the important point is that you could give it to a friend, not that you give it to a coworker. In fact, even from a selfish point of view, the friendship is important: if a coworker asks this of me who isn't already a friend, then I'm less likely to spend energy in arguing with any password request, and so will simply grant it reflexively.
