To stop unwanted purchases by you, or your family members, you can password protect the Play Store app. Check if this feature is enabled on your Play Store or just enable it. It is simple and requires only a few taps. Follow below steps.
Open Play Store app, tap the menu button or the three dots on the top right and then tap ‘Settings’. It will open the Play Settings.
Under ‘User Controls’ check the box against ‘Password’. It will ask you to enter the password (It is your regular password for the Google account associated with the device).
Enter the password and confirm it. Also, when you purchasing an app, don’t forget to uncheck the ‘Never ask me again’ box when the password pop-up appears. That’s it! Next time anyone tries to purchase an app, game or anything you will be asked to enter a password. Though it can be inconvenient, irritating and time consuming, it is the safest way to prevent any unwelcome purchases and app installation on your Android phone.
