This one in particular -- I use KeePass for my personal stuff, still; but at work, there seem to be a ton of logins we need to share.
Never mind sensitive stuff -- we get lots of use out of LastPass for managing the list of test and demo users on our site. We setup sandbox accounts (with various types of users) for potential customers. Each time the main logins to into LastPass, so if they run into problems, anyone on the dev team can help them out (with no other coordination required).
I've not been terribly impressed by LP's usability, honestly; but for quite a while they've seemed to be the only mature product in this space.
I've noticed Dashlane seems to be catching up here; I'm keeping an eye on them.
Group credentials and secure keys for production environments, among other things, can be shared using LastPass.
