As originally released, the NBC Profile registration flow kept all sign up methods on one screen and prioritized signing up with Facebook. Testing found two valuable insights about this.
NBC users generally felt a sense of distrust with Facebook. Additionally, splitting registration methods and the Sign Up with Email form into two screens actually made the flow feel easier to users. Choosing a sign up method before being presented with the Sign Up with Email form reduced users’ cognitive load and made it look “…like it was going to be less effort.” (Quote from user test)
Amending the flow to use two separate screens also helped future-proof it from becoming overwhelming as it grew from two sign up methods (Email and Facebook) to four methods (including Google and Apple ID). To address discomfort with Facebook, the sign up methods screen now puts Sign Up with Email option first.
