Today we're expanding our official Third-party Auth integrations to include [Clerk](https://clerk.com).

[Third-party Auth](/docs/guides/auth/third-party/overview) allows you to use external Auth providers with the Supabase as a drop-in replacement for Supabase Auth. This modular design is [intentional](/docs/guides/getting-started/architecture#product-principles), allowing you to pick and choose features of Supabase. Our platform makes it easy to get started with Postgres and *any* of your favorite tools.

It was [already possible](/partners/integrations/clerk) to use Clerk with Supabase, however the previous method was a bit of a hack that required sharing your project's secret and JWT templates from Clerk. We've worked with the Clerk team on the new implementation. Now you can enjoy better security and the same developer experience you've come to expect from Supabase.

To get started with Clerk and Supabase, visit Clerk's [Connect with Supabase](https://dashboard.clerk.com/setup/supabase) page.

Register your Clerk domain [in the Supabase Dashboard](/dashboard/project/_/auth/third-party) or in the CLI:

```toml
[auth.third_party.clerk]
enabled = true
domain = "example.clerk.accounts.dev"
```

In your JavaScript app all you need to do is write the following code:

```tsx
import { createClient } from '@supabase/supabase-js'

const SUPABASE_URL = 'https://<supabase-project>.supabase.co'
const SUPABASE_ANON_KEY = '<SUPABASE_ANON_KEY>'

const supabase = createClient(SUPABASE_URL, SUPABASE_ANON_KEY, {
  accessToken: () => {
    return Clerk.session?.getToken()
  },
})
```

## Third-Party Auth is now a lot cheaper

One more thing: today we're making Third-party Auth cheaper so that it has pricing parity with Supabase Auth.

You can have up to 50,000 MAU on the Free plan, or 100,000 MAU on the Pro plan and $0.00325 per MAU above that number.

|            | Free Plan            | Pro Plan              |
| ---------- | -------------------- | --------------------- |
| Previously | 50 MAUs included     | 50,000 MAUs included  |
| Now        | 50,000 MAUs included | 100,000 MAUs included |
