User Registration Flows

Configuring registration on a website for the first time, or supplementing an existing registration requires planning to ensure the optimal user experience. This document will highlight common registration scenarios, and provide best practices to detect the state of returning users.

Scenarios
My site only uses Facebook for Registration
If you do not currently have any existing registered users, or you are starting a brand new website, we recommend this approach for simplicity. The Registration Plugin will streamline the Registration process for Facebook users by pre-filling many fields, and for all non-Facebook users, provide a simple form that can be easily integrated into your website.
My site uses Facebook and my own Registration
Adding Facebook to your own registration/authentication system can add a few complexities. Specifically, if a user registers with Facebook, and you already have an account for that user (detected via identical e-mail address or browser cookie), those accounts should immediately be merged.
