Getting started with Git and GitHub
Setting your username in Git
Git uses a username to associate commits with an identity. The Git username is not the same as your GitHub Enterprise username.
Caching your GitHub password in Git
If you're cloning GitHub repositories using HTTPS, you can use a credential helper to tell Git to remember your GitHub username and password every time it talks to GitHub.
Why is Git always asking for my password?
If Git prompts you for a username and password every time you try to interact with GitHub, you're probably using the HTTPS clone URL for your repository.
Updating credentials from the OSX Keychain
You'll need to update your saved username and password in the git-credential-osxkeychain
helper if you change your password or username on GitHub.
