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?

I think you may have the wrong Git repository URL.

Open .git/config and find the [remote "origin"] section. Make sure you're using the SSH one:

ssh://[email protected]/username/repo.git

You can see the SSH URL in the main page of your repository if you click Clone or download and choose ssh.

And NOT the https or git one:

https://github.com/username/repo.git
git://github.com/username/repo.git

You can now validate with just the SSH key instead of the username and password.

If Git complains that 'origin' has already been added, open the .config file and edit the url = "..." part after [remote origin] as url = ssh://github/username/repo.git

The same goes for other services. Make sure the address looks like: protocol://something@url

E.g. .git/config for Azure DevOps:

[remote "origin"]
    url = https://[email protected]/mystore/myproject/
    fetch = +refs/heads/*:refs/remotes/origin/*
