Three-year-old buys pink convertible on eBay

As a extra safety step, I though to do a BIN, bid, or ask the seller a question you still have to type your passocode in to confirm, even if you're logged in. Maybe I'm wrong.
 
my 1 year old niece grabs the mouse every chance she gets. She can't even see the keyboard but her little hand is clicking away at the mouse just like she sees her auntie do. I can imagine her clicking BIN but i don't know about the confirmation steps. It seems a little farstretched...but hey anything is possible
