Using built-in authentication
When you use the default authentication method, all authentication details are stored within your GitHub Enterprise Server instance. Built-in authentication is the default method if you don’t already have an established authentication provider, such as LDAP, SAML, or CAS.
You can create a custom message that users will see on the sign in page. For more information, see "Customizing user messages on your instance."
