Google fix 30 minute purchase issue

In the news recently there has been some complaint with regards to the fact that if you were to purchase something in Google Play Store on Android, you have 30 minutes to install as much as you want without reentering that password.
It looks like you have the ability to change this in the Google Play Store settings, I’d recommend asking for a password every time if you are handing your device to your children, or, don’t hand your device to your children. Do they REALLY need those magical fantasy fish?
