Query: KeyAuth: Bringing Public-key Authentication to the Masses   Passwords are a fragile, inadequate, and insecure tool for authenticating
users, and are especially fraught with problems when used to secure access to
network resources and services. In many cases, passwords provide a false sense
of security. Creating passwords which are both secure (i.e., hard for attackers
to guess) and easy for humans to remember is, at best, a paradoxical task
because these two criteria are diametrically opposed. Fortunately, a far more
secure and user-friendly alternative is available. Public-key cryptography
provides a means of both identifying and authenticating users without the need
for passwords. KeyAuth is a generic and universal implementation of public-key
authentication aimed at supplanting password-based authentication and
significantly improving the security of network accessible resources by
enhancing the usability of frequently used authentication mechanisms. KeyAuth
is an application-, language-, operating system-, and protocol-independent
public-key authentication service.
