Is it possible to share consent across different main domains?

Can we collect consent for a group of websites or is consent always limited to a website?

If you'd like to share consents across multiple domains, you would first need to inform correctly the user on the notice (we can help there by checking your wording) and then we'll help you config the banners accordingly so that consents are stored on a 3rd party domain (like mycompagny.privacy-center.org).

Then if a user consents on a first website, he/she will not have to see the consent message again.

Yes, you can share consent across different main domains by using the "Group Cookies" functionality.

This allows the consent to be stored on a subdomain that you own and delegate to us, such as privacy.your-domain.com.

The consents will be shared only between the domains that have this feature activated with the same specific subdomain.

This enables private consent among all your sites without third-party exposure. For more details, such as limits & obligations, please refer to the Didomi documentation here.
