function useAuthenticateWithJWT(): {
  authenticateWithJWT: (options?: {
     idempotencyKey?: string;
  }) => Promise<AuthenticateWithJWTResult>;
};
Hook that provides access to authenticate end users with developer-issued JWTs. Use this when integrating with third-party identity providers (Auth0, Firebase, Cognito, etc.). Important: Before using this hook, you must:
  1. Configure custom auth in the CDP Portal (JWKS endpoint, issuer, etc.)
  2. Provide a customAuth.getJwt callback in your CDP initialization config

​
Returns

{
  authenticateWithJWT: (options?: {
     idempotencyKey?: string;
  }) => Promise<AuthenticateWithJWTResult>;
}
NameType
authenticateWithJWT()(options?: { idempotencyKey?: string; }) => Promise<AuthenticateWithJWTResult>

Examples

// React - With Auth0
import { useAuth0 } from '@auth0/auth0-react';
import { useAuthenticateWithJWT } from '@coinbase/cdp-hooks';

function AuthButton() {
  const { getAccessTokenSilently } = useAuth0();
  const { authenticateWithJWT } = useAuthenticateWithJWT();
  const [error, setError] = useState(null);

  const handleLogin = async () => {
    try {
      // Authenticate with CDP (uses customAuth.getJwt callback)
      const { user, isNewUser } = await authenticateWithJWT();

      console.log('Authenticated user:', user);
      if (isNewUser) {
        console.log('New user created with wallet!');
      }
    } catch (err) {
      setError(err.message);
    }
  };

  return (
    <div>
      <button onClick={handleLogin}>Sign In with Auth0</button>
      {error && <p>Error: {error}</p>}
    </div>
  );
}

// React Native - With Auth0

  const handleLogin = async () => {
    try {
      // Step 1: Trigger Auth0 login (opens browser)
      await authorize();

      // Step 2: Authenticate with CDP
      const { user, isNewUser } = await authenticateWithJWT();
