I am suggesting an idea which would utilize having set up 2FA using a phone number to count for chat verification as well.
I was in a raid but when I got to the destination streamer I couldn't send messages in the chat even though I had followed that channel. I got a message saying that I couldn't chat because my account wasn't verified. I clicked on the little info icon, and it explained it and I was able to get into chat fine.
I was confused though, because I have had my Twitch account set up with 2FA using my phone number for a while, easily more than 3 months. I thought that would suffice as enough for having my account verified. I was really confused when the system gave me the verification code to use before I had entered my phone number to the system. I know that's because of how Google Authenticator works, but still confusing that it worked.
I'm just thinking that, because the layers of security are identical for setting up 2FA and chat verification, fulfilling one requirement could be counted as fulfilling the other. I don't think this would decrease security at all but it would improve the user experience. I know that it would take some coding work to make that happen, but I think the time would be worth it.
