"""
Authentication provider implementations for Mail Intake.

---

## Summary

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.
