"Why not simply remember your passwords?"
I have a few dozen dozen long, randomly generated passwords for various things (ignoring web site logins, etc.). While I certainly remember the three I use the most, it's beyond my ability to remember them all. A password vault (or a written list of the passwords, but vaults are encrypted) is a necessity.
That said, I wouldn't use any that communicate over the network.
