Context

The app currently supports Google and GitHub login via Better Auth. Adding Apple expands the login options, especially for iOS users.

What to do

Add Apple as a social login provider in Better Auth.

Files to change

apps/api/src/lib/auth.ts — add apple to the socialProviders config in the betterAuth() call. Requires clientId and clientSecret from env vars.
.env.example — add APPLE_CLIENT_ID and APPLE_CLIENT_SECRET placeholders.
Production .env on VPS — add Apple credentials once obtained.
apps/web/src/routes/login.tsx — add a 'Continue with Apple' button calling signIn.social({ provider: 'apple', callbackURL: window.location.origin }).

Acceptance criteria

Users can sign in with their Apple account
A user row is created on first Apple login (same as Google/GitHub flow)
Login works in both dev (localhost) and production (lilastudy.com)
Apple callback URI is registered in Apple Developer Console for both environments

Prerequisites

Apple Developer account with Sign in with Apple configured
Service ID and key generated in Apple Developer Console

Notes

Better Auth docs: https://www.better-auth.com/docs/authentication/social-sign-in
Apple Sign in with Apple requires a paid Apple Developer account ($99/year). Evaluate whether the user base justifies this cost before starting.
