1) The problem → All/most of my customers have facebook accounts, and I'd like them to be able to login with those accounts.
2) Why is this important → Improves sign up conversion rates and reduces the time required to login.
3) What will happen if this goes unsolved → I'll need to build a custom solution or continue to miss out on a % of my leads.
4) Possible solutions → Give us the option to add Facebook auth to the pre-built signup/login UI or to a custom UI.
