The Storage Access API can help deliver a smooth and personalized user experience while respecting privacy boundaries. It enables a variety of use cases where cross-site data access is necessary for a seamless user experience. Here are some common scenarios:
- Embedded content: Storage Access allows embedded content (for example, comment providers, plugins, dashboards, maps, videos) to access stored information across the sites where they appear. This is crucial for preserving user settings, maintaining sessions, and providing consistent functionality. See When to use the Storage Access API over other APIs for a deeper dive.
- Related Website Sets: When used in conjunction with Related Website Sets, Storage Access offers even greater flexibility. A user interaction is still required but the requirement for a user prompt is relaxed, and the embedding site can directly request storage access on behalf of embedded content originating from a related site. This streamlines the process while still maintaining user privacy.
