How to change a password for Jupyter notebook

Hi @alexey,
I used these same steps and it worked, although I don’t bother with the --config option as the path you show seems to be the default.

Care to post a sample password and hash?

If you are using the Amazon AMI builds then you should see that this field is populated, you can find the default password in the setup video I believe. (http://course.fast.ai/lessons/aws.html)
