Login with Authentication key

Due to some changes in the website (we think about new anti-bot protections) login with E-Mail/Password could cause "Incorrect password" error, even when the credentials are correct.

Then to avoid this problem a new login method has been added, the Authentication key.

The Authentication key is a file created by a software (or script). This software will open the web browser in your computer, and will ask you to login in to Netflix web page.

After the login in the web page, the software will create the Authentication key file, and provide you of a PIN.
With this file+PIN (the password will be still required) you can login on any device (or system) where you have installed Kodi with Netflix add-on and so bypass the problem of "Incorrect password" error.

How to get the file NFAuthentication.key and the PIN

You can create the NFAuthentication.key file from any Personal Computer with Linux (e.g. Ubuntu), Mac or Windows (desktop / laptop). You cannot execute it on Kodi OS's (e.g. LibreELEC) or gaming console.
