While the [page view](views/index.html) is loading, [GPT](https://developers.google.com/publisher-tag/reference#googletag) auto-loads the Secure Signal UID2 script which pushes the advertising token to GPT local storage, and the [IMA](https://developers.google.com/interactive-media-ads/docs/sdks/html5/client-side) makes an ad request which transmits the encoded signal in the request. The [page view](views/index.html) calls the [init()](https://unifiedid.com/docs/sdks/client-side-identity#initopts-object-void) function again, but this time without passing an explicit identity. Instead, the identity is loaded from the first-party cookie. |

 |  5   | Keep the application main page open, or refresh it after a while, and note the UID2 identity state, updated counter, and login information values. | In the background, the UID2 SDK continuously validates whether the advertising token is up to date, and refreshes it automatically when needed. If the refresh succeeds, the user opts out, or the refresh token expires, the callback function is invoked, and the UI elements are updated with the current state of the UID2 identity. For details, see [Workflow Overview](https://unifiedid.com/docs/sdks/client-side-identity#workflow-overview) and [Background Token Auto-Refresh](https://unifiedid.com/docs/sdks/client-side-identity#background-token-auto-refresh).                                                                                                                                                                                                          |
