Password problem

My laptop did some kind of reset and wiped out my username and password. Since I haven't had to enter a password for so long, I tried a couple that I though it might be and they didn't work. So I clicked on the link "forgot password" and got a temporary one, but now I can't figure out how to replace it with something I might be able to remember if I had to. Can you direct me to where I can reset my password please?

If you click on "settings" on the top right, it will take you to a place where there's a list of options. One of them is for changing your password
