Guide to integrating Web3Auth for social login in Web3 dApps. Covers email, Google, Apple, Discord, and Twitter login flows. MPC key management, session handling, RainbowKit integration, and migration from traditional wallet-only flows. Zero-friction onboarding.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Web3Auth Integration Guide
Web3Auth enables social login (Google, Apple, email) for Web3 apps. Users get a wallet without knowing what a wallet is. Zero-friction onboarding for DeFi.
## Why Web3Auth?
| Traditional Flow | Web3Auth Flow |
|-----------------|--------------|
| 1. Install MetaMask | 1. Click "Sign in with Google" |
| 2. Create wallet | 2. Done ✅ |
| 3. Write down seed phrase | |
| 4. Fund with ETH for gas | |
| 5. Start using dApp | |
## Architecture
```
User clicks "Sign in with Google"
│
▼
Web3Auth SDK → OAuth Provider (Google, Apple, etc.)
│
▼
MPC Key Generation (threshold splitting)
│
├── Share 1: Device (browser)
├── Share 2: Web3Auth network
└── Share 3: Recovery (optional)
│
▼
Ethereum wallet created silently
│
▼
User is logged in with a wallet, no seed phrase needed
```
## Quick Start
```bash
npm install @web3auth/modal @web3auth/ethereum-provider
```
```typescript
import { Web3Auth } from '@web3auth/modal';
import { EthereumPrivateKeyProvider } from '@web3auth/ethereum-provider';
const chainConfig = {
chainNamespace: 'eip155',
chainId: '0xa4b1', // Arbitrum One

How to install
mdr add nirholas/three.ws/web3auth-integration-guide@sha256:8f9be7a6c8301174The line at the top of this page pins the label git:20260501.87cefc9, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
