Hi there, 
I'm trying to install your addon on a raspberry pi and it keeps giving the Login error.
I tried doing NFAuth on linux and it keeps saying :
Traceback (most recent call last):
  File "NFAuthenticationKey.py", line 20, in <module>
    import websocket  # pip install websocket-client
ImportError: No module named websocket

I have websocket already installed and all.

Then I tried on a windows PC and it keeps giving me:

Bad JSON escape sequence \P. Path 'chromeExePath', line 5, position 24.

Any ideas how I can solve this?

have you fixed this issue? I have got the same error as you

I have just fixed the issue, it was caused by two different versions of python were installed on my Mac, you need to direct the environment to the latest python and that will fix the problem.
