JaCarta U2F by Aladdin-RD provides strict authentication in online services according to the FIDO U2F standard. It is a universal USB token used as a second factor for password authentication in online services that support the FIDO U2F standard, including cloud services (Dropbox, Google Cloud Platform), email services (GMail), file hosting (Google Drive), video hosting (YouTube), IT project collaboration hosting (GitHub), electronic payment systems (Google Wallet), and social networks (Facebook, Google Currents). The device is compatible with the JaCarta Management System. It is registered in the registry of Russian software for computers and databases (No. 4300). JaCarta U2F strengthens user password authentication for access to web resources through two-factor authentication using a token, eliminating the need for users to remember complex passwords. The use of two-factor authentication can significantly reduce password complexity requirements. The device allows one token to access multiple web resources, limited only by the token's memory capacity for storing authentication data. Each private key stored in the token's memory and used to access a specific resource is linked to the address of that resource (URL), providing phishing protection. The main components of a typical U2F authentication solution based on JaCarta U2F include a web server, web application, U2F server, and U2F client. The JaCarta U2F token interacts with the computer through the HID interface, requiring no driver installation as they are already included in modern operating systems: Windows, Linux, Mac OS X. During registration, a new pair of public-private keys is generated within the token, linked only to the online service. The public key is sent to the server, while the private key never leaves the token, safely stored in the token's memory.
