I have been launching Jupyter Notebook for years using the following command:
jupyter-notebook --port=7000 --no-browser --no-mathjax
When I try to open the jupyter on the browser it ask me for a password, even though I have never set any before.
It is important to note that If I do set the port to a value different than 7000 (eg., the default 8888)
the interface will open with no problem
I am running jupyter locally, and on the following setup:
Python 3.5.2
With the following modules installed:
jupyter (1.0.0), jupyter-client (4.4.0), jupyter-console (5.0.0), jupyter-core (4.2.1), ipykernel (4.5.2), ipython (5.1.0), ipython-genutils (0.1.0), nbconvert (4.3.0), nbformat (4.2.0), notebook (4.3.0)
NOTE: I have no jupyter configurations file
Following are some of the output lines from the server:
[I 19:16:24.358 NotebookApp] Serving notebooks from local directory: /Users/my_user_name
[I 19:16:24.358 NotebookApp] 0 active kernels

[I 19:16:24.358 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
And follwing are messages after I try to open it on the browser (using port 7000)

At this point there is a page from jupyter asking me to insert a password I have never set before.
SOLVED!
With latest update of notebook module (4.3.1) the problem has been solved.
Once the jupyter notebook is launched the user is prompted to paste a URL into the browser at the first connection:
Copy/paste this URL into your browser when you connect for the first time,
to login with a token:
http://localhost:7000/?token=32be0f5ee74cfe521187bc479855ce8b9fbab9e8021701c9
This solved the problem!
You can remove the password completely with:
Without
--NotebookApp.password=''
, when connecting from a remote computer to a local Jupyter launched simply with:it still asks for a password for security reasons, since users with access can run arbitrary Python code on the server machine!
Tested on Jupyter 4.4.x.
Notebook 4.3.0 has enabled login security by default. The token to enter in the password field is printed in the output of the notebok server during startup (or can be included directly in the URL)
See http://jupyter-notebook.readthedocs.io/en/latest/security.html#server-security for more info, including disabling the feature.
However, this would not explain why you get the password prompt when running on one port but not on another
For me, the solutions described above was not applicable in Docker.
The following solution works like a charm on Linux:
Details:
tensorflow/tensorflow:latest-py3-jupyter
Steps to start Jupyter in Docker with your pre-defined password:
export JUPYTER_TOKEN='password'
docker run -it --rm -p 8888:8888 -u $(id -u ${USER}):$(id -g ${USER}) -e JUPYTER_TOKEN=$JUPYTER_TOKEN -v /home/<user>/jupyter:/tf/ tensorflow/tensorflow:latest-py3-jupyter
For me, that is the easiest way to get rid of the annoying token authentication.
The same issue occured on my machine since the last update of the jupyter-notebook package. After installing version
it prompted me for a password I never set. Downgrading to
worked for me keeping the system a productive environment. Of course this is just a fast patch.
I also wondered where the password was set since I don't have an explicit config file in my
.jupyter
-folder. Setting up my own withmade no difference.
How to avoid "Invalid credentials" by disabling jupyter Notebook Password & Token
First open Anaconda Prompt
made changes into the following command
Now launch the jupyter notebook from anaconda navigator definitely the problem will be resolved as soon..
If you are trying to run from
docker
without password just useCMD
like bellow:
