| About SSH | Using the SSH protocol, you can connect and authenticate to remote servers and services. With SSH keys, you can connect to {% data variables.product.product_name %} without supplying your username and personal access token at each visit. |

When you set up SSH, you'll generate an SSH key and add it to the ssh-agent and then add the key to your {% data variables.product.product_name %} account. Adding the SSH key to the ssh-agent ensures that your SSH key has an extra layer of security through the use of a passphrase. For more information, see "Working with SSH key passphrases."
{% if currentVersion == "free-pro-team@latest" %}To use your SSH key with a repository owned by an organization that uses SAML single sign-on, you'll need to authorize it first. For more information, see "Authorizing an SSH key for use with SAML single sign-on."{% endif %}
We recommend that you regularly review your SSH keys list and revoke any that are invalid or have been compromised.
{% if currentVersion == "free-pro-team@latest" %} If you haven't used your SSH key for a year, then {% data variables.product.prodname_dotcom %} will automatically delete your inactive SSH key as a security precaution. For more information, see "Deleted or missing SSH keys." {% endif %}
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 {% data variables.product.product_name %} account. For more information, see "About SSH certificate authorities."
