From Cookies to Cryptography: Hardware-Bound Sessions End Account Takeover

Stolen session cookies represent a critical security vulnerability enabling complete account takeover, yet existing defense mechanisms can only reduce exposure rather than eliminate it. Device Bound Session Credentials (DBSC) fundamentally solves this by binding sessions to device-level hardware cryptography, rendering stolen cookies useless since they cannot be replayed without hardware signatures. This transition marks a paradigm shift from bearer token authentication toward hardware-validated credentials.
