How to disable password request for a Jupyter notebook session?
<p>I have been launching Jupyter Notebook for years using the following command:</p>
<pre><code>jupyter-notebook --port=7000 --no-browser --no-mathjax
</code></pre>
<p>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 <code>7000 (eg., the default 8888)</code> the interface will open with no problem</p>
<p><strong>I am running jupyter locally, and on the following setup:</strong></p>
<pre><code>Python 3.5.2
</code></pre>
<p><strong>With the following modules installed:</strong></p>
<pre><code>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)
</code></pre>
<p><strong>NOTE: I have no jupyter configurations file</strong></p>
<p>Following are some of the output lines from the server:</p>
<pre><code>[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] The Jupyter Notebook is running at: http://localhost:7000/?token=aa0dab6e2d85766f3e2e4f0f6633e4473db56a56c94cac76
[I 19:16:24.358 NotebookApp] Use Control-C to stop this server and shut down all kernels (twice to skip confirmation).
</code></pre>
<p>And follwing are messages after I try to open it on the browser (using port 7000)</p>

<p>At this point there is a page from jupyter asking me to insert a password I have never set before.</p>
<h2>SOLVED!</h2>
<p>With latest update of notebook module (4.3.1) the problem has been solved.</p>
<p>Once the jupyter notebook is launched the user is prompted to paste a URL into the browser at the first connection:</p>
<pre><code>Copy/paste this URL into your browser when you connect for the first time,
to login with a token:
    http://localhost:7000/?token=32be0f5ee74cfe521187bc479855ce8b9fbab9e8021701c9
</code></pre>
<p>This solved the problem!</p>
