OPAQUE: The Best Passwords Never Leave your Device

Passwords are a significant security issue due to their vulnerability during transmission and storage. Even when encrypted, passwords can be leaked and broken with effort. OPAQUE is a cryptographic protocol that enables password usage without ever leaving the user's possession, thus ensuring greater security. It is an example of systems that allow password-based authentication while maintaining privacy. Although it requires significant changes to existing infrastructure, OPAQUE offers promising potential for enhancing password security in the meantime.
