I also really like the "go to this website on your computer and enter this code" for logging in to Apple TV, Chromecast, etc so you aren't typing a 30 character password on a TV remote.
If you remembered your password, you could login normally. If not, they would email you the 'forgot password' link, but there was no requirement to set a new password! I only logged in once every few months and could never remember the password, so for me just using it as a magic link system worked well, but frequent users would not be inconvenienced by it since they could use the normal login process.
I hate this with a passion. I'm all comfy in my chair, ready to watch something, and I get the message that I have to get up and go to my computer and do stuff when all I want to do is watch TV. So I watch something else that doesn't require a computer to watch on TV.
