# Basic usage of Authentication APIs

```js
const { AuthenticationClient } = require('forge-server-utils');
const { FORGE_CLIENT_ID, FORGE_CLIENT_SECRET } = process.env;
const auth = new AuthenticationClient(FORGE_CLIENT_ID, FORGE_CLIENT_SECRET);
const authentication = await auth.authenticate(['bucket:read', 'data:read']);
console.log('2-legged Token', authentication.access_token);
```
