Share data amongst a small group of sites
Publishers often need to share data across multiple sites to power seamless user experiences, such as:
- Content recommendations: Providing personalized content recommendations across related sites.
- Single sign-on: Enabling users to sign in once and access multiple affiliated sites.
- Synchronized user preferences: Maintaining consistent user preferences across related platforms.
These use cases can be achieved using Related Website Sets in combination with Storage Access API.
