Web3Auth is where passwordless auth meets non-custodial key infrastructure for Web3 apps and wallets. By aggregating OAuth (Google, Twitter, Discord) logins, different wallets and innovative Multi Party Computation (MPC) - Web3Auth provides a seamless login experience to every user on your application.

...and a lot more

For using Web3Auth in the web, you have two choices of SDKs to get started with.

Web3Auth Plug and Play Modal SDK @web3auth/modal: A simple and easy to use SDK that will give you a simple modular way of implementing Web3Auth directly within your application. You can use the pre-configured Web3Auth Modal UI and whitelabel it according to your needs.

Web3Auth Plug and Play NoModal SDK @web3auth/no-modal: The nomodal module implementing all the Web3Auth features you need and giving you the flexibility of using your own UI with the Web3Auth SDK working in the backend.

npm install --save @web3auth/modal

Hop on to the Web3Auth Dashboard and create a new project. Use the Client ID of the project to start your integration.

Web3Auth needs to initialise as soon as your app loads up to enable the user to log in. Preferably done within a constructor, initialisation is the step where you can pass on all the configurations for Web3Auth you want. A simple integration for Ethereum blockchain will look like this:

import { Web3Auth } from "@web3auth/modal";

//Initialize within your constructor
const web3auth = new Web3Auth({
  clientId: "", // Get your Client ID from Web3Auth Dashboard
  chainConfig: {
    chainNamespace: "eip155",
    chainId: "0x1",
  },
});

await web3auth.initModal();

Once you're done initialising, just create a button that triggers to open the login modal for the user on their request. Logging in is as easy as:

await web3auth.connect();

Packages	@latest Version	Size	Description
🏠 No-Modal
