Jupyterhub REMOTE_USER Authenticator

Authenticate to Jupyterhub using an authenticating proxy that can set the REMOTE_USER header.

Architecture and Security Recommendations

This type of authentication relies on an HTTP header, and a malicious client could spoof the REMOTE_USER header. The recommended architecture for this type of authentication requires that an authenticating proxy be placed in front of your Jupyterhub. Your Jupyerhub should only be accessible from the proxy and never directly accessible by a client.

This type of access is typically enforced with network access controls. E.g. in a simple case, the host on which the Jupyterhub service accepts incoming requests has its host based firewall configured to only accept incoming connections from the proxy host.

Further, the authenticating proxy should make sure it removes any REMOTE_USER headers from incoming requests and only applies the header to proxied requests that have been properly authenticated.


This package can be installed with pip either from a local git repository or from PyPi.

Installation from local git repository:

cd jhub_remote_user_authenticator
pip install .

Installation from PyPi:

pip install jhub_remote_user_authenticator

Alternately, you can add the local project folder must be on your PYTHONPATH.


You should edit your :file:`` to set the authenticator class:

c.JupyterHub.authenticator_class = 'jhub_remote_user_authenticator.remote_user_auth.RemoteUserAuthenticator'

You should be able to start jupyterhub. The "/hub/login" resource will look for the authenticated user name in the HTTP header "REMOTE_USER" [1]. If found, and not blank, you will be logged in as that user.

Alternatively, you can use RemoteUserLocalAuthenticator:

c.JupyterHub.authenticator_class = 'jhub_remote_user_authenticator.remote_user_auth.RemoteUserLocalAuthenticator'

This provides the same authentication functionality but is derived from LocalAuthenticator and therefore provides features such as the ability to add local accounts through the admin interface if configured to do so.

[1]The HTTP header name is configurable. Note that NGINX, a popular proxy, drops headers that contain an underscore by default. See for details.
