New identity primitives for the agentic era

Agents create auth challenges traditional
systems weren’t built for

Delegated consent flows:

Ensure users authorize every agent action.

On-behalf-of
actions:

Agents execute tasks on behalf of users

Dynamic client registration:

Securely handle agents that appear on demand.

Ephemeral
clients:

Agents spin up and vanish on the go

Scoped, time-bound tokens:

Limit each agent’s access to exactly what’s needed.

Over-provisioned
access:

Agents often hold more permissions than needed

Unified
audit logs:

Trace every action across human → agent → tool

No
audit trail:

Agent-driven actions lack end-to-end visibility.

Data protection, security, compliance — fully baked in

Encrypted

Bank-level data protection

AES-256 encryption secures data at rest and TLS 1.3 for data in transit. Client secrets are hashed using Bcrypt. Authorization codes and user PII are temporarily cached, never stored

Restricted

Restricted Access

Customer data is logically separated, with strict access controls ensuring data is restricted to the right account

Certified
