jupyter prompts for password

[Mazzaroth M.]

Hi all, I'm using the websauna python web framework and when I go through the tutorial and open the default jupyter notebook, it prompts me with a password. What is the password? I never created a default_config.py nor used the passwd() command to generate and set a hash. This is on Ubuntu Mate 16.04 running on a raspberry pi 3. I'm pretty sure this is jupyter 5.1.0

To see what I mean, please check out the gist I made.

BTW here is the websauna tut page. https://websauna.org/docs/tutorials/gettingstarted/tutorial_06.html

Also, if I DO create a default_config.py nor used the passwd() command to generate and set a hash(which creates a .jupyter dir in my home dir), I see "Invalid Password" when I attempt to use it.

Dear Micheal

Token authorization was added in v4.3, please see the question on github:
https://github.com/jupyter/notebook/issues/1979

And the following links for more info:

Thanks, I pasted in the token and now I can login.

However I now have a different issue: I get the message: "A connection to the notebook server could not be established. The notebook will continue trying to reconnect. Check your network connection or notebook server configuration."

I've confirmed that any python commands I enter have no impact to the runtime. Any ideas?

Hi all,

This is indeed a recent change done for security reason. It seem we
had a few issues opened since the release:

https://github.com/jupyter/notebook/issues/1987
https://github.com/jupyter/notebook/issues/1980
https://github.com/jupyter/notebook/issues/1944

We did overlook a few case, but we are between a rock and a hard
place, as there are some serious security implications of not having a
password/token, but making is usable at the same time is not easy.

We did not had much feedback on the change either before it was released.

We'll try to get a 4.3.1 out that fix some of the usability issues

Thanks,
