![]() Paste the text below, substituting in the email address for your account on GitHub Enterprise Cloud. Insert your hardware security key into your computer. For more information, see " Error: Unknown key type." If you are using macOS or Linux, you may need to update your SSH client or install a new SSH client prior to generating a new SSH key. Generating a new SSH key for a hardware security key For more information, see " Adding a new SSH key to your GitHub account." ssh-add ~/.ssh/id_ed25519Īdd the SSH public key to your account on GitHub. If you created your key with a different name, or if you are adding an existing key that has a different name, replace id_ed25519 in the command with the name of your private key file. Host Īdd your SSH private key to the ssh-agent. If your SSH key file has a different name or path than the example code, modify the filename or path to match your current setup. The private file name one has no special suffix and commonly ends the algorithm like id.rsa. You can use HTTPS Git URLs, using a personal access token for authorization: in this case, you dont need an SSH key: Configuring HTTPS authorization. Generate public and private SSH keys ssh-keygen -f /root/.ssh/github-my-repo.id.rsa. If you already have them, you can skip this step. Open your ~/.ssh/config file, then modify the file to contain the following lines. There are several options for generating an SSH keypair. If the file doesn't exist, create the file. $ open ~/.ssh/config > The file /Users/YOU/.ssh/config does not exist. If you're using macOS Sierra 10.12.2 or later, you will need to modify your ~/.ssh/config file to automatically load keys into the ssh-agent and store passphrases in your keychain.įirst, check to see if your ~/.ssh/config file exists in the default location. For example, you may need to use root access by running sudo -s -H before starting the ssh-agent, or you may need to use exec ssh-agent bash or exec ssh-agent zsh to run the ssh-agent. $ eval " $(ssh-agent -s)" > Agent pid 59566ĭepending on your environment, you may need to use a different command. One could install Git for Windows and subsequently run ssh-add. After you generate the key, you can add the public key to your account on to enable authentication for Git operations over SSH. You can generate a new SSH key on your local machine. For more information, see 'Adding a new SSH key to your GitHub account. ssh-add /.ssh/ided25519 Add the SSH public key to your account on GitHub. For more information, see the OpenSSH 8.2 release notes. If you created your key with a different name, or if you are adding an existing key that has a different name, replace ided25519 in the command with the name of your private key file. You must connect your hardware security key to your computer when you authenticate with the key pair. If you want to use a hardware security key to authenticate to GitHub Enterprise Cloud, you must generate a new SSH key for your hardware security key. For more information, see " Checking for existing SSH keys." You can generate SSH keys quickly in two other ways: through the command line, using Windows Subsystem for Linux (WSL), or with PuTTY. Default storage location is in the C:\Users folder. ![]() ![]() If you're unsure whether you already have an SSH key, you can check for existing keys. Generate SSH keys on Windows 10 or 11 by using Command Prompt, PowerShell, or Windows Terminal and entering 'ssh-keygen' followed by a passphrase. If you don't already have an SSH key, you must generate a new SSH key to use for authentication. The SSH agent manages your SSH keys and remembers your passphrase. ![]() If your key has a passphrase and you don't want to enter the passphrase every time you use the key, you can add your key to the SSH agent. Whenever you use the key, you must enter the passphrase. When you generate an SSH key, you can add a passphrase to further secure the key. When you connect via SSH, you authenticate using a private key file on your local machine. We will be using GitHub as our Git hosting service in the following examples, but others will work just as well.You can access and write data in repositories on using SSH (Secure Shell Protocol). In order to be able to clone a remote Git repository using the SSH protocol, you will have to create a new SSH key pair on your local machine, and add this key to your Git hosting service. Moreover if the SSH key file was to be stolen, it won’t give access to the account itself (unlike the credentials) and can be easily revoked. In that sense, SSH is a more secure method for cloning repositories and pushing / pulling commits, as only the machines with the key file on disk are able to access the repositories. On the other hand, when using SSH, Git uses your SSH key to authenticate, which means that you don’t need to send your credentials over the network. When using HTTPS, Git will prompt you for your username and password during the authentication process. The main difference between cloning a remote repository with SSH and HTTPS is the way the authentication is handled. ![]()
