User Authentication—Passwords and Beyond

User Authentication—Passwords and Beyond

On March 25, Jim Fenton, a leading expert on user-centric identity and Internet privacy, is presenting a lecture on the widest-deployed way of authenticating users—about passwords. He will describe their advantages and disadvantages or the possibilities of supplementing them. The lecture takes place within the FIT Informatics Evenings from 19:00 in the T9:107 auditorium.


Passwords have been around for a long time and are by far the widest-deployed way of authenticating users. While passwords have definite security limitations, they remain popular for low to moderate security applications. They are a key component, something you know, in multi-factor authentication.

But as authentication threats have become more sophisticated, higher security authentication, mostly involving the use of multiple authentication factors, has been needed for more applications. Some of these provide little more than a false sense of security, while others provide excellent protection against a comprehensive range of threats. The choice of authentication products and methods is not straightforward and depends on the types of devices being used, the nature of the application, and the expected range of threats.

This lecture will discuss the characteristics of password-based authentication and several additional authentication modes that can be used to supplement passwords, the threats addressed (and not addressed) by each, and how best to build a comprehensive authentication solution that meets both the application’s and users’ needs.

About the Event

The lecture is free of charge, and registration is not required. It is intended for the audience with basic knowledge of the topic.
