Filtered Social Login

Hi Dan.

I have 3 users jon@gmail.com, bob@gmail.com and fred@gmail.com. I want the 3 of then to access my app via auth0.com social login using their Google credentials. However I want ensure that only Jon, Bob and Fred can login. I don’t want anyone with a Google account to be able to access my app.

I believe I should create a rule. However I want to make it easy for me to add and remove users without having to edit a rule. It would be good I could just add gmail addresses to a database or just a file which the rule checks.
