Google Play has a password protection feature that requires you to enter a password before each purchase. To set it up:
- Open the Google Play Store app on your mobile device
- Go to the Menu icon > Settings
- Select Require authentication for purchases and choose a setting
- Complete the setup by following the on-screen instructions
You are strongly advised to turn on password protection in the Play Store as ookyo will not be responsible for any accidental/unwanted purchases that are charged to your ookyo account. However, you may be able to get a refund from Play Store or from the app developer. For more information, click here.
