​
Overview

Magic’s authentication can enable passwordless Web3 onboarding (no seed phrases) using multiple configurable methods. Each method either creates an account address for the user (non-custodial) or utilizes an existing account address. This is handled completely by Magic with out-of-the-box UI, with no lift from the integrating dApp.

​
Compatibility

The Login UI is available via the following client-side SDKs:

​
Use Cases

  • Allow your users to log in and/or sign up to your dApp using their preferred authentication method and gain access to their public wallet address on the network you are connected to.
  • You can collect a signed token for wallet address verification and skip the need to explicitly request a personal signature which would prompt an additional screen.

Authentication Methods

​
Email One-Time Passcode

If a user chooses to authenticate through their email, they will receive a unique code to their email that is generated per attempt and the user will be required to enter it to authenticate. OTPs for email provide a simple and effective way to increase security and ensure the safety of user assets.

​
Usage

​
Login

JavaScript
import { Magic } from "magic-sdk"

const magic = new Magic('YOUR_PUBLISHABLE_API_KEY', {
  network: "sepolia",
});

const accounts = await magic.wallet.connectWithUI();
The example above authenticates the user and connects to the Ethereum Sepolia Testnet. To connect to a different network, simply replace the configuration with another of the 30+ chains supported by Magic.
