The Cross-Device Consent Sharing is a special feature, which is available to Enterprise clients and needs to be activated for your Settings-ID. |

How does it work?
Controller-ID is a unique and random ID that we assign to a user's device the first time they visit a page. We store it in the device itself. We need this Controller-ID information to assign consent data to a user/device. If the local storage is cleared, then an already existing user will be considered as a new user and will be assigned a new controller ID, when he will visit again the website.
What to consider
As a customer, you should not use the controller-ID attribute inside the CMP Script Tag during implementation because the use of Controller-ID to get consent information is not allowed by Usercentrics and this may lead to erroneous results for consent history.
The use of the controller-ID attribute in our CMP Script Tag is only allowed, in case you have permission from Usercentrics to use the Cross-Device Consent Sharing.
Please check with your CSM if you are interested to have the Cross-Device Consent Sharing feature for your Usercentrics Settings-ID.
