Organization owners can manage an organization's SSH certificate authorities (CA).

You can allow members to access your organization's repositories using SSH certificates you provide by adding an SSH CA to your organization. You can require that members use SSH certificates to access organization resources,, unless SSH is disabled in your repository. For more information, see "About SSH certificate authorities."

Adding an SSH certificate authority

When you issue each client certificate, you must include an extension that specifies which GitHub Enterprise user the certificate is for. For more information, see "About SSH certificate authorities."
