[FIXED] Change jupyter notebook server password

Issue

I would like to change my jupyter notebook server's password to something else. I see on Jupyter's documentation (http://jupyter-notebook.readthedocs.org/en/latest/public_server.html) how to prepare a password for ostensibly a new server but not how to change an existing one.

Can I simply:

1. Generate a new SHA hash for a password as the documentation above specifies
2. Replace the password in the PWDFILE environment variable (located in jupyter_notebook_config.py)
3. Restart the jupyter server

Basically, I'm asking because I don't want to confuse and/or mess up the authentication system by just changing things.

Solution

Reposting as an answer:

The process to change the password should be just the same as setting it in the first place. Jupyter hashes the password you enter, and compares it with the hash it loaded from the config file. It doesn't copy the hash to any other persistent storage (though it does store it in memory, so you will need to restart the notebook server).

I'm not sure how environment variables are involved - I don't think the instructions use any for the password.
