guestauthenticator is an Authenticator plugin for JupyterHub. It allows users to sign into the hub anonymously. An accompanying clean-up script may then be configued as a JupyterHub service. This script periodically deletes the resulting orphaned anonymous accounts.
An example of how to configure this is below:
# Set guestauthenticator as the authentication mechanism for the hub
c.JupyterHub.authenticator_class = 'guestauthenticator.GuestAuthenticator'
