Jupyter Password Not Hashed

Question

When I try to set up the jupyter notebook password, I don't get a password hash when I open up the jupyter_notebook_config.json file.

This is the output of the json file:

{
"NotebookApp": {
  "password": 
 "argon2:$argon2id$v=19$m=10240,t=10,p=8$pcTg1mB/X5a3XujQqYq/wQ$/UBQBRlFdzmEmxs6c2IzmQ"
 }

}

I've tried running passwd() from python as well, like in the instructions for Preparing a hashed password instructions found online but it produces the same results as above. No hash.

Can someone please let me know what I'm doing wrong?

I'm trying to set up a Jetson Nano in similar fashion to the Deep Learing Institute Nano build. With that build you can run Jupyter Lab remotely so the nano can run headless. I'm trying to do the same things with no luck.

Thanks!

This is the default algorithm (argon2):

https://github.com/jupyter/notebook/blob/v6.5.2/notebook/auth/security.py#L23

you can provide a different algorithm like sha1 if you like:

>>> from notebook.auth import passwd
>>> from notebook.auth.security import passwd_check
>>>
>>> password = 'myPass123'
>>>
>>> hashed_argon2 = passwd(password)
>>> hashed_sha1 = passwd(password, 'sha1')
>>> 
>>> print(hashed_argon2)
argon2:$argon2id$v=19$m=10240,t=10,p=8$JRz5GPqjOYJu/cnfXc5MZw$LZ5u6kPKytIv/8B/PLyV/w
>>>
>>> print(hashed_sha1)
sha1:c29c6aeeecef:0b9517160ce938888eb4a6ec9ca44e3a31da9519
>>> 
>>> passwd_check(hashed_argon2, password)
True
>>>
>>> passwd_check(hashed_sha1, password)
True 

Check whether you don't have a different Jupyter server running on your machine. It happened to me that I was trying over and over a password on port 8888 while my intended server was on port 8889.

Another time, Anaconda started a server on localhost:8888, and I was trying to reach a mapped port from a docker container, also on port 8888, and the only way to access was actually on 0.0.0.0:8888.
