Você pode acessar e gravar dados em repositórios em dados your GitHub Enterprise Server instance usando o SSH (Protocolo Secure Shell). Ao se conectar por meio do SSH, você se autentica usando um arquivo de chave privada no computador local. For more information about SSH, see Secure Shell on Wikipedia.
When you set up SSH, you will need to generate a new private SSH key and add it to the SSH agent. You must also add the public SSH key to your account on GitHub Enterprise Server before you use the key to authenticate. For more information, see "Generating a new SSH key and adding it to the ssh-agent" and "Adding a new SSH key to your GitHub account."
You can further secure your SSH key by using a hardware security key, which requires the physical hardware security key to be attached to your computer when the key pair is used to authenticate with SSH. You can also secure your SSH key by adding your key to the ssh-agent and using a passphrase. For more information, see "Working with SSH key passphrases."
To maintain account security, you can regularly review your SSH keys list and revoke any keys that are invalid or have been compromised. For more information, see "Reviewing your SSH keys."
If you're a member of an organization that provides SSH certificates, you can use your certificate to access that organization's repositories without adding the certificate to your account on GitHub Enterprise Server. You cannot use your certificate to access forks of the organization's repositories, if the forks is owned by your personal account. For more information, see "About SSH certificate authorities."
