Make passwd and passwd_check compatible with jupyter notebook

[CaselIT]

Hi,

I'm trying to configure jupyterlab to use a password. I initially created the password with jupyter notebook password but it does not work with jupyterlab.
After some digging I think the problem is that while jupyter notebook updated the passwd and passwd_check to use a more secure algorithm in jupyter/notebook#3793, jupyter_server (and also ipython) did not.

Any reason not to update it here also?

Also a bit ot, how come there are 3 implementation of the same things that look identical?

Hi @CaselIT, we discussed this today at the server team meeting.  The history is that the ipython project split into several projects that included jupyter notebook.  They are now distinct products.  We should however allow jupyter notebook passwords to work with the jupyter server during a transition phase.  We agreed to detect a jupyter notebook password and use it if there is not one set on jupyter server, but warn the user.  As for jupyter/notebook#3793, we've added it to the Running list of Notebook PRs to port.

from the outside I though it was actually all integrated, since I can use lab/notebook on the same server etc.

Thanks for the reply. Since it's already tracked in the other issue, we could close this if you prefer

We can leave this open to track "allow jupyter notebook passwords to work with the jupyter server"

cf #450 for the port.  Regarding the backwards compat, it is already handled when using nbclassic, which is installed when you install JupyterLab 3.0+.

Thanks!
