No, my child was playing the game. The game is not my banking app, and even my banking app requires authorization on top of clicking a button. Merely clicking a button in a game is not financial authorization, and it's harmful to accept this as if it's normal. It's not.
I'm not hostile, I'm just explaining that playing a game is not the same thing as authorizing a financial transaction. I don't understand why you insist that they are.
An online financial transaction should at the very least require a password or pin code. Preferably a redirect to my bank where I authorize the transaction through my bank's authorization mechanism (which uses 2FA). I go out of my way to disable everything that doesn't do that, including pin-less NFC payments on my bank card. At the time, I'd also set Google Play Store to always require a password (which should really be the default), and yet it executed a payment without it.
To suggest that a simple button click in a game played by children should be enough to access my money is ridiculous.
It's how most of my online transactions are. When I buy online, I'm redirected to my bank's website to authorize the transaction. That's exactly how I want it. Only Google and Amazon and a few others require less secure transactions for some reason. I don't like that.
