# Access Token Device Information

Access tokens now include detailed device information through the new `.device` property, providing better insights into how users access your application.

### Migration from .agent

The `.agent` property has been deprecated and replaced with `.device`.

### Device Properties

The `.device` object contains detailed information about the user's device, browser, and application:
