This forces GitHub to always use SSH, even for HTTPS URL's! This way, you can use
https:// GitHub URL's and they will still use your SSH key.
git config --global url."[email protected]:".insteadOf "https://github.com/"
When you clone an HTTPS URL, it now gets rewritten as an SSH URL.
Alternatively, this forces GitHub to always use HTTPS. Great for macOS, where you can use git-credential-osxkeychain to store your GitHub token.
This will not rewrite
[email protected]:user/repo.git URL's, though, so I don't really recommend it! Besides, SSH keys are often easier to manage than API tokens.
git config --global url."https://github".insteadOf git://github
Hat tip to these people!
