Skip typing a password and set up fingerprint authentication for your Google Play purchases.
Before the latest version of Android, only one option existed for keeping Google Play purchases secure: entering your password. But if you're using Android 6.0 Marshmallow -- on devices like the Nexus 5X or Nexus 6P -- then you've gained the ability to authenticate with your fingerprint instead.
Using a fingerprint is faster than typing in a complex password, and gives you the final decision on purchases if you share an account with someone else. Here's how to set it up:
Note: You will need to have fingerprint security enabled for this setting to work. For more information on setting this up, check out this post.
Step 1: Head to the Google Play store, open the slide-out menu and head to Settings.
Step 2: Scroll down to Fingerprint authentication and tap the check box next to it.
Step 3: Enter your password when prompted, and you're set.
Now you can skip typing in a password for any Google Play purchases. Instead, you'll see a pop-up asking for your fingerprint.
