Ask HN: How are you sharing passwords between colleagues for projects?

We have various machines that a few of us need full access too, however these machines are only accessible by TeamViewer and have a few programs running that also have their own set of login login details.<p>Originally, one person kept all information in Excel as a passworded file and shared it with others, but now we really need to move to something more secure that can be accessed and updated by multiple people at the same time.
