preventing all new software installation

[gopack116]

Looking to prevent installation of apps of all kinds, or at least prevention of accessing recently downloaded apps.
I have the play store locked with a PIN, but accessing play.google.com allows for app installation just as easily. Looking for a method to set a PIN by default on all apps downloaded, or prevent any new software installation without a PIN, regardless of application used to access the installation prompts.
Thanks very much.

Go to the play store, goto settings, choose do not update. Done.

Installation from the Play Store requires your Google login credentials. If you haven't given them to someone else then nobody can install apps that way. I guess I'd need to know more about the circumstances here.

I'm guessing you give your phone to others unsupervised?

Do you have a pin?

What version android? (Marshmallow has provision for multiple users which might help although I'm not that familiar with it)

Disable the GlueGull play$tore app.

If you need to use it:

1) Enable Airplane Mode (which disables data and wifi)
2) Enable and start play$store
3) Reenter your play$tore download updates settings preferences if needed
4) Disable Airplane Mode

When finished using play$tore, DISABLE it.

It's easy. Access play.google.com with your web browser, then log out and don't remember password.
