FederationIdentity

Why this is canonical

Federated identity is a mature, standards-backed concept (SAML, OAuth, OpenID Connect) that is now confronting a new challenge: agents and AI systems that must authenticate and authorize across organizational boundaries at machine speed. The .ai TLD marks this as the agent-era evolution of a proven infrastructure concept.

Where it fits

A few directions this coordinate opens —

Agent Identity and Authentication
Federated identity infrastructure for AI agents that must authenticate across organizational and trust boundaries.
Identity, access management, and agent infrastructure builders
AI-Augmented Identity Platforms
Extending existing federated identity infrastructure with AI for anomaly detection, adaptive auth, and intelligent access.
IAM platform vendors and enterprise security teams

Illustrative, not exhaustive — held as a transferable canonical position, open to the buyer's own use.
