Адаптер Рутокен Web Плагин is a free browser add-on that allows users to utilize the functionality of the Рутокен Web Plugin. The main purpose of the Рутокен Web product is to replace insecure "login-password" authentication with two-factor hardware authentication.

The first factor of authentication is the presence of a USB token called Рутокен Web, and the second factor is knowledge of the unique PIN code associated with it. This solution is based on electronic signature technology and eliminates the risk of theft or unauthorized use of user accounts on web resources.

The Рутокен Web capabilities are designed to prevent theft of the hardware device itself, as well as forgery or substitution of electronic signatures through the use of trojans, phishing, or traffic interception. This cross-platform and multi-browser solution is cost-effective and user-friendly.

The product consists of three components: a USB token, a browser plugin, and a server-side implementation for signature verification. The USB token acts as an electronic key and performs electronic signatures without the need for driver installation. The browser plugin facilitates communication between the USB token and the browser, requiring no administrative privileges for installation. It utilizes browser APIs and does not require additional components or platforms such as Java or Microsoft Silverlight. The server-side component supports various platforms and development tools, including PHP, ASP.NET, WordPress, Joomla, and Bitrix.

In the event of a lost token, users can access the website once without the USB token by using a one-time access code printed on a scratch card included in the Рутокен Web package. This access recovery mechanism ensures the uninterrupted use of web resources.
