    note

    Google Client ID is the OAuth Client ID obtained from the Google Developer dashboard and it's a required field.

Example​

import { Web3Auth } from "@web3auth/modal";
import { OpenloginAdapter } from "@web3auth/openlogin-adapter";

const clientId = "BPi5PB_UiIZ-cPz1GtV5i1I2iOSOHuimiXBI0e-Oe_u6X3oVAbCiAZOTEBtTXw4tsluTITPqA8zMsfxIKMjiqNQ";
// get it from https://dashboard.web3auth.io by creating a Plug n Play project.

const web3auth = new Web3Auth({
  clientId,
  web3AuthNetwork: "sapphire_mainnet",
  chainConfig: {
    chainNamespace: "eip155",
    chainId: "0x1",
    rpcTarget: "https://rpc.ankr.com/eth",
    displayName: "Ethereum Mainnet",
    blockExplorer: "https://goerli.etherscan.io",
    ticker: "ETH",
    tickerName: "Ethereum",
  },
});

const openloginAdapter = new OpenloginAdapter({
  adapterSettings: {
    uxMode: "popup",
    loginConfig: {
      // Google login
      google: {
        verifier: "w3a-google-demo", // Pass the Verifier name here
        typeOfLogin: "google", // Pass on the login provider of the verifier you've created
        clientId: "519228911939-cri01h55lsjbsia1k7ll6qpalrus75ps.apps.googleusercontent.com", // Pass on the Google `Client ID` here
      },
    },
  },
});
web3auth.configureAdapter(openloginAdapter);

// Initialize Modal
await web3auth.initModal();

// Login with Google
await web3auth.connect();
