Prevent accidental or unwanted purchases

You can help prevent accidental purchases on your device from the Play Store app by turning on authentication. Authentication means certain information, like a password, must be entered on your device to make a purchase.

Turn authentication on or off

Authentication settings apply only to the active account on the device where you add them. If you use your Google Account on more than one device, repeat the steps below for each device. If you use multiple accounts on your device, repeat the steps below for each account on the device.

On your mobile device

Choose your authentication setting

  1. Open the Google Play Store app Google Play.
  2. Touch the Menu icon Google Play Store Menu Icon > Settings.
  3. Touch Require authentication for purchases.
  4. Choose a setting.
  5. Follow the on-screen instructions.

 

Set up fingerprint authentication (on select devices)

If your device allows fingerprint authentication, you can approve Google Play purchases with a fingerprint scan.

You'll only be prompted for fingerprint authentication if the app requires it or you've followed the steps above to require authentication for purchases.

  1. Open the Google Play Store app Google Play.
  2. Touch the Menu icon Google Play Store Menu Icon > Settings.
  3. Check the box next to "Fingerprint authentication."
  4. Enter a password. You'll only need to enter a password when you first set up fingerprint authentication.

Note: To change authentication settings you will need your Google password. Visit account recovery if you don't remember your password. 

On Android TV
  1. Open the Google Play Store app Google Play.
  2. Select Settings > Purchase authorization.
  3. Choose a setting.
  4. Follow the on-screen instructions.

Note: To change authentication settings you will need your Google password. Visit account recovery if you don't remember your password. 

 

What authentication settings mean

For all purchases through Google Play on this device: Authentication is required for every digital content purchase through Google Play (including within apps).

Every 30 minutes: Every time you authenticate for a purchase, you can continue to buy all forms of digital content through Google Play (including within apps) for the next 30 minutes without authenticating again.

Never: Authentication is not required for purchases. Disabling authentication may result in unauthorized purchases. You assume responsibility for all charges.

Family-friendly content: Authentication is always required for purchases through Google Play within apps designated for ages 12 and under.

Tip: When you create a family on Google Play, your family members can use the family payment method to make purchases through Google Play.
