There are several ways to clone repositories available on GitHub.
When you view a repository while signed in to your account, the URLs you can use to clone the project onto your computer are available below the repository details:
For information on setting or changing your remote URL, see "Changing a remote's URL."
Cloning with HTTPS URLs (recommended)
https:// clone URLs are available on all repositories, public and private. These URLs work everywhere--even if you are behind a firewall or proxy.
git pull, or
git push to a remote repository using HTTPS URLs on the command line, you'll be asked for your GitHub Enterprise username and password.
When 2FA is enabled
For example, when you access a repository using Git on the command line using commands like
git pull or
git push with HTTPS URLs, you must provide your GitHub Enterprise username and your personal access token when prompted for a username and password.
For more information on setting up two-factor authentication, see "Adding security to your account with two-factor authentication."
Cloning with SSH URLs
SSH URLs provide access to a Git repository via SSH, a secure protocol. To use these URLs, you must generate an SSH keypair on your computer and add the public key to your GitHub Enterprise account. For information on setting up an SSH keypair, see "Generating an SSH key."
git pull, or
git push to a remote repository using SSH URLs, you'll be prompted for a password and must provide your SSH key passphrase.
Tip: SSH URLs can be used locally, or as a secure way of deploying your code to production servers. You can also use SSH agent forwarding with your deploy script to avoid managing keys on the server.
Cloning with Subversion
You can also use a Subversion client to access any repository on GitHub. Subversion offers a vastly different feature set than Git; for a quick overview, see "What are the differences between Subversion and Git?"
