KaKao Social Login with Web3Auth

note

Kakao login can be performed in various ways, depending on the use case. We have demonstrated this with Auth0, but this can be done with any other Federated/JWT providers.

Create a KaKao verifier

• Go to the Web3Auth dashboard and select your project. Click on the Custom Authentication tab, then click on the Create Verifier button to create a new verifier.

  

1. Create a verifier for your Auth0 application by selecting Auth0 as the Login provider from this modal. 2. Select the KaKao as the Authentication Type based on the dropdown. 3. Enter the Auth0 Client ID and Auth0 Domain from your Auth0 application. See how to create a new Auth0 application here.

4. Add the KaKao Social Connection to your Auth0 application.
5. Click on the Create button to create KaKao Custom Authentication via Auth0 verifier.

Example

import { AuthAdapter } from "@web3auth/auth-adapter";

// Create AuthAdapter instance once you have created Web3AuthNoModal instance
const authAdapter = new AuthAdapter({
  adapterSettings: {
    loginConfig: {
      jwt: {
        verifier: "w3a-auth0-demo", // Pass the Verifier name here
        typeOfLogin: "jwt", // Pass on the login provider of the verifier you've created
        clientId: "hUVVf4SEsZT7syOiL0gLU9hFEtm2gQ6O", // Pass on the Auth0 `Client ID` here
      },
    },
  },
});

web3AuthNoModalInstance.configureAdapter(authAdapter);

// Initialize
await web3AuthNoModalInstance.init();

// Login with Kakao
await web3AuthNoModalInstance.connectTo(WALLET_ADAPTERS.AUTH, {
  loginProvider: "jwt",
  extraLoginOptions: {
    domain: "https://web3auth.au.auth0.com", // Pass on the Auth0 `Domain` here
    verifierIdField: "sub", // Pass on the field name of the `sub` field in the JWT
    connection: "kakao", // Use this to skip Auth0 Modal for Kakao login
  },
});
