What’s the easiest auth system to integrate with Google and Apple sign in?

If you want the easiest auth system for Google + Apple sign-in, the usual top choices are:

1) Firebase Authentication

Best for: Fastest setup, especially for mobile apps and simple web apps.

Why it’s easy:

• Built-in support for Google and Apple
• Great SDKs for iOS, Android, web
• Handles user sessions and account linking
• Very common, lots of examples

Downside:

• Can feel limiting if you want highly custom auth flows
• Some advanced features may require extra work

---

2) Auth0

Best for: Easier than rolling your own, more flexible than Firebase.

Why it’s easy:

• Supports Google and Apple out of the box
• Nice hosted login pages
• Good docs and enterprise features
• Works well for web apps and backend APIs

Downside:

• More expensive than Firebase as you scale
• Slightly more setup than Firebase

---

3) Supabase Auth

Best for: If you already want Postgres + backend in one place.

Why it’s easy:

• Supports Google and Apple OAuth
• Good for modern web apps
• Integrates nicely with Supabase database/storage

Downside:

• Apple setup can be a bit more fiddly than Google
• Less polished than Auth0 for auth-specific features

---

My quick recommendation

• Mobile app / simplest overall: Firebase Auth
• Web app with more control: Auth0
• Already using Supabase: Supabase Auth

If you want, I can also give you a “pick one based on your stack” answer for:

• iOS / Android
• React / Next.js
• Flutter
• backend-only API
