This is a relatively simple authenticator for small or medium-sized JupyterHub applications. Signup and authentication are implemented as native to JupyterHub without relying on external services.

NativeAuthenticator provides the following features:

• New users can signup on the system;
• New users can be blocked from accessing the system awaiting admin authorization;
• Option of enforcing password security by disallowing common passwords or requiring a minimum password length;
• Option to block users after a set number of failed login attempts;
• Option of open signup without need for initial authorization;
• Option of asking more information about users on signup (e-mail).
• Option of requiring users to agree with given Terms of Service;
• Option of protection against scripting attacks via reCAPTCHA;
• Option for users with an org-internal e-mail address to self-approve via secure link;
