Old computer died, can't get on old email

My old computer died (all in one and the screen/everything just went poof) so like all my passwords went poof. I had a yahoo email with 2 step verify on but whenever I go to log into that specific email it asks to send a code to my phone or one of my recovery emails. I get the code on my phone or on my other recovery email but yahoo blocks me (probably cause its a new computer but dude a hacker isn't going to have my phone). So anyways I can't get in.

I know I had club pogo for like 3 months and I wanted to log in/play but its saying my username isn't valid (MenSuckBigTime3) I know it was back in the day when you could actually change your username and by the time I was over that stage they blocked you from changing. Anyways that was the username and the email which I have zero ways to access (though i have the recovery email/phone codes but yahoo isn't letting me in). I thought maybe I used this account to log in but its not showing anything for clubpogo or history which makes me think it was my other email.

I need a way to reset my password without being able to log in or I'll have to just tell my bank to block clubpogo. Seriously frustrating trying to get into all my old accounts and getting locked out because I'm on a new pc (also my PW for my yahoo is the right PW) but I have no clue what is going on there so just a suggestion folks start writing your passwords in a physical book in your house/updating them as time goes on with dates so you don't end up in a position like me where you can't access most of your stuff (highly annoying/frustrating experience).
