Staying logged in and connection QoL
I don't use Twitch daily, which means almost everytime I do want to use it, I've been logged out. Which means I have to go to my password manager, unlock it, copy-paste my password, open my emails, input a verification code, go back to my emails to delete the one for the code and the one that lets me know I just logged in, and only then can I see IF the streamers I follow are live and IF I wanna watch their stream.
Most of the time I just give up at step "I see I've been logged out" because it's not worth going through all that just to check whether or not there is content I want to watch - which makes me not use Twitch very often, which makes it log me out, etc.
Please let us choose to "remember me" and do so for a very long time, just like on Youtube where I'm never logged out unless I manually do so. Please also let us choose to trust devices, and don't require a verification code anymore (or very rarely) for those devices that we consider safe. It might seem little but I'm sure it'd be a huge QoL improvement for many people.
