I can't sign in to support. I need to reset second password

I'm having the same issue it just keeps telling me to sign in when im already signed in

If you are Steam-only, then it is a bug with the support site that causes the sign-in loop. If you have a linked Microsoft account, you can use that to submit the ticket, otherwise it is a matter of waiting until it is fixed (though it may not hurt to check every-so-often since it appears that some Steam-only users have been able to get through after multiple attempts).
