Setup
Add Facebook Login in ~10 minutes
Two steps. A one-time OAuth setup, then one-click sign-in for every member. No backend code.
The Backend
Create a Facebook App
Create a Facebook app, then open Settings › Basic to copy your App ID and App Secret (click Show to reveal the full secret). Paste both into Memberstack under Settings › Auth Providers › Configure Facebook, toggle it on, and add your redirect URI under Facebook Login › Settings.
The Frontend
Add the Button to Your Site
Copy Memberstack's pre-built Facebook button (light or dark) into your Webflow signup or login form. It already carries data-ms-auth-provider="facebook". Add data-ms-social-auth-allow-signup to let new visitors create accounts, then publish.
That's it. Two steps, and your members can sign in with Facebook.
