Introduction

Amazon Cognito lets you add user sign-up, sign-in, and access control to your web and mobile apps quickly and easily. Amazon Cognito scales to millions of users and supports sign-in with social identity providers, such as Apple, Facebook, Google, and Amazon, and enterprise identity providers via SAML 2.0 and OpenID Connect.

Quick start

      {content}
    </AuthProvider>;
  )
}

2. Enable useAuth hook

import { AuthContext } from "@/contexts/CognitoContext";
        
const useAuth = () => {
  return useContext(AuthContext);
};
