# Re-Authorization

An application connection might expire after a period of inactivity. Additionally, new features, such as the [Hubspot Sensitive Fields capability](https://docs.stacksync.com/connectors/authorization/pages/bzMyoXSgwrbwQH7oOlSx#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

The standard authorization process for the specific app will begin. Follow it to successfully reauthorize the connection.
