# Summary

Authentication provider implementations for Mail Intake.

This package defines the **authentication layer** used by mail adapters
to obtain provider-specific credentials.

It exposes:

- A stable, provider-agnostic authentication contract.
- Concrete authentication providers for supported platforms.

Authentication providers:

- Are responsible for credential acquisition and lifecycle management.
- Are intentionally decoupled from adapter logic.
- May be extended by users to support additional providers.

Consumers should depend on the abstract interface and use concrete
implementations only where explicitly required.
