This is a good idea for bookmarks to resources etc. However, you should not be sharing passwords in a shared profile because at the end of the day you would want to be able to go back and check which user made a particular change or authorized something or leaked data etc and if everyone uses the same password you can't do that.

A search for why shared passwords are bad gives us a whole lot of other reason why you shouldn't share/have common passwords.

Another problem is that if a user fat fingers and deletes something they will impact everyone that uses that profile. Or if they log in to a personal account at any site (ecommerce/medical/mail) and save the password they are essentially giving access to that account to everyone else who uses that profile
