What to do if your Jupyter Notebook for beginners asks for a password or token
Problems faced
――One morning, when I tried to open the Jupyter Notebook, the following screen appeared.
―― "Well, I haven't set a password and where can I get the token?"
--Search variously on Google and Qiita to solve yourself as usual

In the first place, this password input screen seems to appear (?) Every time you start Jupyter Notebook. But in my case I have never seen it. I've started it about 50 times already. It is unknown why it was the current timing.
Apparently
1 $ jupyter notebook --generate-config
2 $ jupyter notebook password
If you enter in the terminal, it will be displayed that you can ** set any password **, so you should have been able to set it.
However, I can't enter it in the Chrome field.

The kettle and formula are the most secure. Of course it's in English. https://jupyter-notebook.readthedocs.io/en/latest/public_server.html
Automatic Password setup
As of notebook 5.3, the first time you log-in using a token, the notebook server should give you the opportunity to setup a password from the user interface.
You will be presented with a form asking for the current token, as well as your new password ; enter both and click on Login and setup new password.__
It was written that, apparently from the password request screen --Any password you want to set --Token If you enter, it will be set.
Get a token
If you look closely, you can see how to get the token on the password request screen.
The command:
jupyter notebook list will show you the URLs of running servers with their tokens, which you can copy and paste into your browser. For example: Currently running servers: http://localhost:8888/?token=c8de56fa... :: /Users/you/notebooks or you can paste just the token value into the password field on this page.
so
$ jupyter notebook list
Of the value returned in
http: // localhost: 8888 /? token = (this is the token) :: / Users / (user name)
Copy and paste this into Chrome's Setup a Password and set any password. I'm glad Chrome remembers the password.
Finally
Since I am a beginner, I think there is a mistake in the term, but please forgive me. Please point out any mistakes in the content.
