How to Manage authentication for Play Store purchases

Yup......If you have other people - particularly pesky kids - using your device, then you want to rest assured knowing that they're not racking up a huge Play Store bill made up of in-app purchases for Candy Crush or whatever other games kids play these days. Here's how to manage the level of authentication required for Play Store purchases:

• In the Play Store app, tap the menu icon, Settings > Require authentication for purchases then choose 'For all purchases through Google Play on this device'. Bear in mind you'll need to do this separately on each Android device you own.
