Hello!
In September 2016, while the world was a little less intense than just now, I apparently had the brilliant idea to let users authenticate to a JupyterHub with a username / password set by admins on a google sheet. I apparently wrote the code and published it, but didn’t publicize it too much - probably because the subsequent few months were very depressing for many reasons.
I’ve found it again today! Presenting, jupyterhub-remotecsv-authenticator. It should still work on latest JupyterHub.
People shouldn’t use this authenticator. nativeauthenticator is much better, and you should use that instead.
Fun blast from the past
