Method and System for Cryptographic Authentication Using Portable Hardware Device for Secure Login

USPTO published patent application US20260100840A1 by inventor Diego Matute on April 9, 2026, disclosing a method for authenticating a user to a resource. The method involves receiving an authentication request at a first system from a remote system, communicating with a portable hardware device coupled to the remote system, and performing cryptographic authentication between the device and the system to determine an authentication result.\n\nAffected parties should monitor this application for potential future enforcement if the patent is granted. Technology companies developing authentication systems and manufacturers of hardware security devices may need to consider this intellectual property when designing similar secure login solutions.
