I've been using Git for a while now, but the constant requests for a password are starting to drive me up the wall.

I'm using Mac OS X and GitHub, and I set up Git and my SSH keys as instructed by GitHub's Set Up Git page.

I've also added the github SSH key to my Mac OS X keychain, as mentioned on GitHub's SSH key passphrases page. My public key is registered with Git.

Nevertheless, every time I try to Git pull, I have to enter my username and password. Is there something other than an SSH key that I need to set up for this?
