# 快速开始

通过 JS-SDK 获取 addressAuthToken，使用步骤如下：

1. 使用 NPM 下载

```shell
npm install --save @relationlabs/auth
```

2. 引入依赖

```js
import {authByMetamask} from '@relationlabs/auth'
```

3. 获取 addressAuthToken

```js
const {addressAuthToken} = await authByMetamask()
```

说明：该 token 是钱包签名获得，用此 token 可调用[登录认证](/relation-one-api/api-zh/api/auth.md)接口换取`unifiedAuthToken`。
