I am about to implement a reception screen view of some data my product holds. This data is not extremely sensitive, but enough so that my customers do not want it just out there on the internet for all to see.
The concept is a smart tv with a built in web browser that displays a webpage hosted by my application. My application requires authentication for all other interaction, but the smart tv does not support authentication. So I would like to secure the page somehow, so it isn't just available for all to see.
The only options I see are:
Security by obscurity. I would really like to avoid this one.
IP Whitelisting. This I could do, but not all my clients have a static IP.
Enter credentials on screen. This is not really feasible and the credentials are lost on reboot. So we cannot do this.
Are there other options I just don't know about.
After some research I found that the best option is the OAuth 2.0 Device Authorization Flow.
The gives the user an experience like the one used when setting up Google Chromecast or AppleTV.
