Apple Authentication

Apple Developer Setup

1. Sign in to the Apple Developer portal

2. Get your Team ID (we'll need it later)

3. Go to Certificates list. Check if your bundle ID already exists (EAS builds create it automatically).

4. If not, click +, select App ID, keep type as App, and create it. Bundle ID must match your code (check /apps/native/env.js).

5. Enable Push Notifications and Sign in with Apple

6. Create a Service ID: Choose Service IDs from dropdown, click +

   • Use an identifier similar to your bundle ID. Click continue and save this Service ID.

7. After creating the service ID, From Service IDs list, click the service ID you created just now

8. Select the App ID from this dropdown (that was created in step 4)

cd packages/backend
npx convex env set AUTH_APPLE_ID YOUR_SERVICE_ID_HERE

9. Click continue

10. Go to Keys section, click +

11. Check Sign in with Apple, click Configure

12. Select your App ID

13. Click Download to get the .p8 file

14. Go to Convex Apple OAuth docs and use the secret generator (this secret generator convex works for Convex and Supabase both, its platform agnostic step):

• Enter your Team ID (step 2)
• Enter Service ID (step 6)
• Upload the .p8 file
• Click Generate secret key

cd packages/backend/convex
npx convex env set AUTH_APPLE_SECRET GENERATED_SECRET_KEY_HERE

Test Your Setup

Run your Expo app on a real device. The "Sign in with Apple" button should trigger the native Apple sign-in sheet and return a valid session.

This part of docs took tooooo much effort I hope it helps alot :)
