Frustrated user account management

[ios-Casper-soi]

I'm seriously considering to just give up as this has been nothing but hyperlinks sending me to paragraphs of useless information, can u PLEASE.m tell me there is a way I can change my security password? I'm able to access my account, but to change anything or to attempt to add my Xbox account it keeps asking for my favourite pets name, I'll be very honest, I can't for the life of me figure it out and there is no forgot your queastion option to go another way around it.
All this so I'm able to create a game face ..
