I need something simpler than Auth0 for authentication

If you want something simpler than Auth0, the best choice depends on what you mean by “simpler”:

• Less setup / faster to ship
• Less pricing complexity
• More control / fewer moving parts
• Just basic login for a small app

Here are the most common simpler alternatives:

1. Clerk

• Very developer-friendly
• Nice prebuilt UI for sign-in/sign-up
• Easy to add email/password, magic links, social login
• Good docs and fast integration

Best if: you want Auth0-like features with less hassle.

2. Supabase Auth

• Simple if you’re already using Supabase
• Good for email/password, magic links, OAuth
• Open-source backend stack
• Easy for small apps and MVPs

Best if: you want a lightweight auth system tied to your database/backend.

3. Firebase Authentication

• Very easy to get started
• Great for mobile and web apps
• Handles social login, email/password, anonymous auth
• Can feel simpler than Auth0 for basic use cases

Best if: you’re okay with Google’s ecosystem and want something quick.

4. Better Auth

• Modern, lightweight auth library
• More “build your own” than managed service
• Good if you want flexibility and a simpler code-first approach

Best if: you want self-hosted or app-owned auth without a big platform.

5. WorkOS

• Simplifies enterprise SSO, not basic consumer auth
• Great for B2B apps
• Less suited if you just need regular user login

Best if: your main pain is enterprise login, not general auth.

My quick recommendation

• For easiest overall: Clerk
• For simplest if you already use a backend/database: Supabase Auth
• For quick and familiar: Firebase Auth

If you tell me:

1. your stack (Next.js, React, Node, etc.),
2. whether you need social login / SSO / magic links,
3. whether you want hosted or self-hosted,

I can recommend the simplest option for your exact case.
