# Web3Auth signer

[Web3Auth](https://web3auth.io/) is a popular embedded wallet provider that supports social logins, making it easier for users to onboard without managing private keys. 

## **Setup**

To use **Web3Auth** with **SDK Core**, first create an application that integrates with Web3Auth.

* Refer to the [Web3Auth documentation site](https://web3auth.io/docs/index.html) for instructions on setting up an application with the Web3Auth.
* For a quick start, Web3Auth provides example starter projects, available [here](https://web3auth.io/docs/examples?product=Plug+and+Play\&sdk=Plug+and+Play+Web+Modal+SDK).

## Integration

After following the Web3Auth documentation, you will have access to a `web3auth` object as shown below that you can pass as an owner to `createSafeSmartAccount`:

<pre class="language-typescript"><code class="lang-typescript">import { CHAIN_NAMESPACES, WEB3AUTH_NETWORK } from "@web3auth/base"
import { Web3Auth } from "@web3auth/modal"
import type { EIP1193Provider } from "viem"
import { EthereumPrivateKeyProvider } from "@web3auth/ethereum-provider"
import { providerToSmartAccountSigner } from "@cometh/connect-core-sdk"


const rpcUrl = process.env.RPC_URL;

const chainConfig = {
    chainNamespace: CHAIN_NAMESPACES.EIP155,
    chainId: "0x66eee", // Hex of 421614
    rpcTarget: rpcUrl,
    displayName: "Arbitrum Sepolia Testnet",
    blockExplorerUrl: "https://sepolia.arbiscan.io/",
    ticker: "AETH",
    tickerName: "AETH",
    logo: "https://cryptologos.cc/logos/arbitrum-arb-logo.png",
  };

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


const web3auth = new Web3Auth({
  clientId,
  uiConfig: {},
  web3AuthNetwork: WEB3AUTH_NETWORK.SAPPHIRE_DEVNET,
  privateKeyProvider,
<strong>});
</strong>
// Initialize for PnP Modal SDK
await web3auth.initModal();
// Trigger the login
await web3auth.connect();
 
// Get the Provider and EOA address (this will be the address of the signer) from Web3Auth
const web3authProvider = web3auth.provider as EIP1193Provider

if (!web3authProvider) {
	throw new Error("No provider found")
}

const signer = await providerToSmartAccountSigner(web3authProvider);
  
</code></pre>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.cometh.io/sdk-core/signers-auth-providers/web3auth-signer.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
