    Discord OAuth2.0 App Client ID and Secret

Set up Discord

  1. Create a verifier for your Discord application by selecting Discord as the Login provider from this modal. Login Providers list on Web3Auth Dashboard
  2. Paste the Client ID from the Discord App(above) to the Client ID field and click on Create. Discord Client ID on Web3Auth Dashboard

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 chainConfig = {
chainNamespace: "eip155",
chainId: "0x1",
rpcTarget: "https://rpc.ankr.com/eth",
displayName: "Ethereum Mainnet",
blockExplorerUrl: "https://etherscan.io",
ticker: "ETH",
tickerName: "Ethereum",
logo: "https://images.toruswallet.io/ethereum.svg",
};

const privateKeyProvider = new EthereumPrivateKeyProvider({ config: { chainConfig } });

const web3auth = new Web3Auth({
clientId,
web3AuthNetwork: "sapphire_mainnet",
privateKeyProvider: privateKeyProvider,
});

const openloginAdapter = new OpenloginAdapter({
adapterSettings: {
loginConfig: {
// Discord login
discord: {
verifier: "w3a-discord-demo", // Pass the Verifier name here
typeOfLogin: "discord", // Pass on the login provider of the verifier you've created
clientId: "1151006428610433095", // Pass on the Discord `Client ID` here
},
},
},
});

web3auth.configureAdapter(openloginAdapter);

// Initialize Modal
await web3auth.initModal();

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

Troubleshoot

Duplicate token found

warning

Receiving Could not get result from torus nodes Duplicate token found error when using Custom verifier for Discord?

  • This is because Discord issues the same token for 30 mins.
  • We revoke it for you for default verifiers( such as when using Web3Auth Modal @web3auth/modal).
  • But when using Custom Verifier for Discord, the integrating dApps have to revoke the token themself before attempting the next login by using discord clientId and secret to revoke the token.

Here's the sample code to revoke the token:

const axios = require("axios").default;
const FormData = require("form-data");

const { DISCORD_CLIENT_SECRET, DISCORD_CLIENT_ID } = process.env;
const { token } = req.body;
const formData = new FormData();
formData.append("token", token);
await axios.post("https://discord.com/api/oauth2/token/revoke", formData, {
headers: {
...formData.getHeaders(),
Authorization: `Basic ${Buffer.from(`${DISCORD_CLIENT_ID}:${DISCORD_CLIENT_SECRET}`, "binary").toString("base64")}`,
},
});

Set up Discord via Auth0

  1. Create a verifier for your Auth0 application by selecting Auth0 as the Login provider from this modal. Discord - Login Providers list on Web3Auth Dashboard

  2. Select the Discord as the Authentication Type based on the dropdown. Discord - Auth0 Authentication Type list on Web3Auth Dashboard

  3. Enter the Auth0 Client ID and Auth0 Domain from your Auth0 application. See how to create a new Auth0 application here.

    Discord - Domain and Client ID from Auth0 Dashboard Discord - Auth0 Client ID and Auth0 Domain on Web3Auth Dashboard

  4. Add the Discord Social Connection to your Auth0 application.

  5. Click on the Create button to create Discord Custom Authentication via Auth0 verifier.

Example

import { Web3AuthNoModal } from "@web3auth/no-modal";
import { OpenloginAdapter } from "@web3auth/openlogin-adapter";
import { EthereumPrivateKeyProvider } from "@web3auth/ethereum-provider";
