For some reason which I now cannot even recall, I set up this computer of mine with a password which has to be entered when it boots up. This has turned out to be an unnecessary hassle in various ways. I would now like to get rid of said password, and just have the thing boot up automatically with no password.

So how do I do it?

Simple question, and I'm sure there is a simple answer, isn't there?

But I cannot seem to find it...
