Twitch requires the most insane password strength I've ever seen. I've had accounts with banks, insurers, court systems and other state/federal government websites, and yours is the only one I will never remember. You're a streaming site. It's not like you're handing out nukes.

Literally all I (and millions of others) want to do is watch streamers and comment occasionally. If the security is this high for streamers, who have jobs and contracts surrounding twitch, then fine. But I think you'd make a lot of people happy by making two separate account types, with different levels of security measures. One for users who will stream, and ones for viewers that will never stream. The latter will be thankful you've made the change, I'm nowhere near the first person to complain, and it's a very stupid reason to lose viewers/users/potential paying customers etc.

I tried to use a password that is autogenerated by my password manager. Obviously I won't put that here, but another one generated by it is: "speed applause deceiver endpoint cash freckles polygraph mothball unsaid raffle vacant unmoved".
This is apparently "not secure" and "too easy to guess". Instead I had to make it: "speed applause deceiver endpoint cash freckles polygraph mothball unsaid raffle vacant unmoved1!"

Its worth pointing out that adding a password requirement of any kind besides length and restricting obvious dictionary sequences is well known (even by the US government via its most recent NIST standards) to result in weaker, not stronger protections, as people tend to follow the same pattern of character replacement in order to meet arbitrary complexity requirements.

Create a better way for old people using the app or have a human suport to help new users on how to create a new account. I have did a tutorial it my self that can be accessed here http://djrudphd.com.br/entrartwitch/ but I gess that is not enough . I guess a that a phone number should be get automaticaly when on a form starts to be filled and after it be sent, Twitch could sent login infos in an SMS with login infos or a button or a link to do the first login where user can fill other options like user name and passaword like WhatsAPP used to do

In Italy they have created a Public Digital Identity System (SPID), for any request within the city or province you must have this Digital Identity.
•
Twitch's problem, I would say the biggest, are threats and insults, a very important solution is the BAN but it's not enough!
•
We must note that there is too much chaos on the web!
•
By applying the SPID system at least in Italy, Twich "Beta" could test this reality and then maybe expand it in Europe and maybe even around the world!
•
With digital identity we will no longer have insults, threats of any kind!
I often read comments in the chat of racist, sexist, homophobic type, with this identity putting the face to the comment we will have much less problems.
•
Let's apply the Public Digital Identity System (SPID) to Twich in Italy! Please!

Thank you!
