I have a server side web application where i want to implement login feature using Auth0. You can create a very basic express project and free auth0 account. All I need is a login screen with two buttons "Login with FB" and " Login with google". Do not use Auth0 Lock or universal hosted page. You should create custom login page and users should be able to login to a private page using fb or google credentials. They should be automatically registered if they are logging for first time. And should remain logged-in until they logout. No need for any styling, just the login feature should be complete in user functionality. Remember it should follow server-side web authentication and best security practices . Also use the auth0 database/metadata stores to save any app or user related data. Let me know if you have any questions.
