Require password for each application to install

by sancho.s   Last Updated April 15, 2019 06:11 AM

Since I will be lending my phone to someone else, I want my phone to ask my Google account password (or alternative authentication) each time an app is installed.

If I go to Google Play -> Three bars menu -> Settings -> Require authentication for purchases, the options are:

  1. For all purchases through Google Play on this device.
  2. Every 30 minutes.
  3. Never.

The first option seems to be what I am looking for. Nevertheless, I am not asked for any authentication for installing apps.

Can this be done? How?

Using a Samsung Galaxy J7, with Android 6.0.1.
