This tool provides hardware-based two-factor authentication for site administrators and users, targeting developers and agencies needing high-security standards. It integrates Yubico OTP security keys to add a physical layer of protection beyond passwords.

Hardware Key Authentication: Users authenticate by inserting or tapping a physical Yubico key, which generates a one-time password. This method is more secure than software-based tokens.

Phishing Resistance: The authentication process is tied to the physical key and the specific site domain, making it highly resistant to phishing attacks that trick users into entering codes on fake sites.

Open-Source Foundation: Built as a fork of a proven project, the code is transparent and can be audited, allowing for community review and contributions to ensure reliability.

Developer-Friendly Integration: Provides hooks and APIs for customizing the authentication flow, making it suitable for integration into complex agency workflows or custom user management systems.

Simplified User Experience: For end-users, logging in becomes a simple action of plugging in a key, removing the need to manage codes from a smartphone app.
