# Workflows

### Workflow A: Single-Use Access

* One verified fulfillment grants one session with a short TTL.
* After expiration, a new session is required.

### Workflow B: Multi-Call Access

* A policy may allow multiple calls within a TTL window.
* Usage is enforced by session policy rules.<br>

### Workflow C: Automated Clients

Automated systems request, fulfill, and reuse sessions until expiration, without login flows.
