Missing notebook.auth submodule?

[apowers313]

Description

notebook.auth disappeared in notebook 7.x?

Importing notebook.auth raises a ModuleNotFoundError. Importing notebook by itself works fine, and it seems that the auth submodule was removed. Works with 6.x and I can't find anything in the changelog that says this API was removed.

Reproduce

As mentioned in countless tutorials, with notebook 7.x installed:

from notebook.auth import passwd
passwd("foo")

Expected behavior

Should yield a hashed password that can be dropped into a config file.

Thanks @apowers313 for opening this issue.

Similar to #7010, this is because Notebook 7 is now based on Jupyter Server.

You can achieve the same result by importing from jupyter_server instead:

from jupyter_server.auth import passwd
passwd("foo")

Maybe this should be documented in the migration guide for visibility: https://jupyter-notebook.readthedocs.io/en/latest/migrate_to_notebook7.html

+1 to documentation. The three places I looked before posting a bug were:

1. Migration notes
2. Changelog
3. Config docs

Maybe the following changes to the docs would help then:

• Migration notes: add new section about using the jupyter_server imports
• Changelog: Move the 7.0 highlights to the top of the changelog for better visibility, since they already include a link to the migration guide.
• Config docs: new section / warning about this change in Notebook 7, and redirect to the Jupyter Server docs.
