SMS login with Facebook Account Kit (legacy)

This page preserves historical context for an SMS login flow using Facebook Account Kit. The current API reference does not document an operation matching the historical POST /auth/sms/facebook route.

The flow depended on project-level Facebook settings and the external Account Kit service; confirm those dependencies before relying on an existing integration.

Do not start a new integration from this page. Use only authentication methods described in the current API reference.
