It’s very useful when using transient
JupyterHub instances in a single physical location. It allows multiple users to log in, but you do not have install a pre-existing authentication setup. With this authenticator, users can just pick a username and password and get to work!## Installation ##You can install this authenticator with:`bash pip installjupyterhub-ndapfirstuseauthenticator`Once installed, configure JupyterHub to use it by adding the following to yourjupyterhub_config.pyfile:`python c.JupyterHub.authenticator_class = 'ndapfirstuseauthenticator.FirstUseAuthenticator' `## Configuration ##### FirstUseAuthenticator.dbm_path ###Path to the [dbm](https://docs.python.org/3.5/library/dbm.html) file, or a UNIX database file such aspasswords.dbm, used to store usernames and passwords. The dbm file should be put where regular users do not have read/write access to it.This authenticator’s default setting for the path to thepasswords.dbmis the current directory from which JupyterHub is spawned.### FirstUseAuthenticator.create_users ###Create users if they do not exist already.When set to False, users would have to be explicitly created before
they can log in. Users can be created via the admin panel or by setting
whitelist / admin list.Defaults to True.## FAQ ###### Why have a password DB and not use PAM ?For security Reasons. Users are likely to set an, insecure password at
login time, and you do not want a brute-force/dictionary attack to manage to
login by attacking via ssh or another mean.#### How can I change my password?To change your password, you should login in your jupyterhub account,
go to<your_server_ip>/hub/auth/change-passwordand change the password.#### I’m getting an error when creating my usernameUsernames cannot contain spaces or commas. Please check if your username is free
of these characters.## SecurityWhen usingFirstUseAuthenticatorit is advised to automatically prepend the
name of the user with a known-prefix (for examplejupyter). This would prevent
for example, someone to log-in asroot, as the created user would bejupyter-root.
