How to Edit FTP info?

I had WordPress set up so all I had to do was hit the Update button and the rest was taken care of. Then I changed my FTP password. Now my WordPress has the old password, but I can’t figure out where to change the FTP settings. Originally, when I would run an automatic update and the password was incorrect, I was given the opportunity to edit the password. Now, I can see my Hostname, FTP Username, and FTP password, but they are grayed out and I cannot edit them. The code says the input areas are disabled.

Does anyone know where I can go to edit my FTP information?
