# Re-Authorization

Re-Authorize your connection.

An application connection might expire after a period of inactivity. Additionally, new features, such as the [Hubspot Sensitive Fields capability](https://docs.stacksync.com/two-way-sync/connectors/authorization/pages/Io5jqkoeBG2XdWcqW2KR#id-3.-optional-check-the-grant-access-to-sensitive-fields-checkbox), may require reauthorization of the app.

#### 1. Open your connection

Click connections on the side nav-bar and then click the connection you want to re-authorize
