`useConsentManager()` is the primary hook for interacting with the consent system. It returns the complete consent store state and all action methods.

```tsx
import { useConsentManager } from '@c15t/react';

function MyComponent() {
  const {
    consents,
    model,
    has,
    saveConsents,
    // ... all state and actions
  } = useConsentManager();
}
```

## identifyUser

The `identifyUser()` method links anonymous consent records to an authenticated user. Call it after a user logs in to associate their consent preferences with their account.

```tsx
import { useConsentManager } from '@c15t/react';

function LoginForm() {
  const { identifyUser } = useConsentManager();

  async function handleLogin(email: string) {
    // ... your login logic
    const user = await api.login(email);

    // Link consent to the authenticated user
    await identifyUser({
      id: user.id,
      identityProvider: 'your-auth-provider', // e.g. 'clerk', 'auth0'
    });
  }

  return (
    <form onSubmit={(e) => {
      e.preventDefault();
      handleLogin(new FormData(e.currentTarget).get('email') as string);
    }}>
      <input name="email" type="email" placeholder="Email" />
      <button type="submit">Log in</button>
    </form>
  );
}
```

> ℹ️ **Info:**
> identifyUser sends the user data to the c15t backend. It works in hosted mode, including the legacy alias mode: 'c15t'. In mode: 'offline', the call is a no-op.
