Not only for people. Beyond individual users, UIID issues verifiable identity credentials to AI agents and automated systems.
Why that matters: If an automated system holds a verifiable identity, its activity stops being anonymous and indistinguishable from a human's. Accountability becomes possible.
How authority works: An agent never receives open-ended access the way a traditional access key often works. It acts under narrowly defined, time-limited permissions tied back to the person or organization that authorized it — stating what it may do and for how long — and those permissions can be revoked at any time.
The bigger picture: Web4 calls this category of automated, agent-driven activity the Synthetic Web. The goal is not to keep agents out, but to make sure they always act under someone's clearly stated authority.
