Use case

Agent-to-agent (A2A) authentication

When agents call other agents, verify identity and preserve who is really acting — across every hop.

Agent-to-agent (A2A) authentication secures the calls agents make to one another. In multi-agent systems, a request may pass through several agents, so each hop needs to prove its identity and carry the delegation chain that says who it ultimately acts for.

The A2A challenge

Each agent must prove its own identity to the next.
The original principal’s authority must travel with the request, scoped and time-bound.
Any hop must be independently verifiable and auditable.
