GitHub AE is currently under limited release.

Managing your organization's SSH certificate authorities

You can add or delete SSH certificate authorities from your organization.

Who can use this feature

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."

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

Adding an SSH certificate authority

If you require SSH certificates for your enterprise, enterprise members should use a special URL for Git operations over SSH. For more information, see "About SSH certificate authorities."
