[FIXED] How to remove password for Jupyter Notebooks and set token again

Issue

I need to do this for Pycharm.

Here are the steps that I did which I'm not able to undo.

1. I added a password for authentication using:
   

   $ jupyter notebook password

2. I then used the below command to comment all the code in jupyter_notebook_config.py

   $ jupyter notebook --generate-config

3. Then I removed the hashed password generated in the jupyter_notebook_config.json which now looks like this

   { "NotebookApp": { "password": "" } }

4. I then did the following changes in jupyter_notebook_config.py file

   c.NotebookApp.password = ''
   c.NotebookApp.token = '< generated>'
   

5. Now, There is no token getting generated and there is no password as well when I start the Jupyter notebook.

   Pycharm git:(master) ✗ jupyter notebook
   [I 21:53:35.158 NotebookApp] Serving notebooks from local directory: /Users/...
   [I 21:53:35.158 NotebookApp] 0 active kernels
   [I 21:53:35.158 NotebookApp] The Jupyter Notebook is running at:
   [I 21:53:35.158 NotebookApp] http://localhost:8888/?token=%3Cgenerated%3E
   
   Copy/paste this URL into your browser when you connect for the first time,
   to login with a token:
   http://localhost:8888/?token=%3Cgenerated%3E
   

Now, how do I make it like the way it was or how do I get the token back??

PS - I even tried jupyter notebook list, but still the same URL is coming. Also, I'm doing this on a mac, so please advise accordingly.

Solution

Hmm my config looks different.

Just remove this file and it will default to making a token

$ cat ~/.jupyter/jupyter_notebook_config.json
{
  "NotebookApp": {
    "password": "sha1:d0a89f391169:9ca771c3518f845438693b938b39703ce1104eaf"
  }
