I work w/ a homeowner association. We want only people with tightly controlled, registered email addresses with roles of WordPress subscribers to be able to authenticate. Is that possible? Then they can connect thru Google, Facebook, etc, correct? Thanks!
I’m not sure I fully understand what your use case is, but if you are using an Auth0 hosted user database, you can certainly “pre-register” your known legitimate users, and then disable signups on that database. Then only the people you have pre-registered will be able to log in.
If you then want your users to be able to log in with their social media credentials, you will need to provide a mechanism to add those credentials to their profiles. A user profile page with buttons for “Add you Facebook login”, “Add your Google login”, etc.
