Passwords weakness has been in the news again lately. But we have known for some time that passwords alone are not a good authentication or access control mechanism. Strong and practical authentication is very challenging. There are “strong” schemes, but they often don’t work well for users. Security practitioners are familiar with the 3 factors of authentication: something you know; something you have, and; something you are. Each of these have fundamental flaws. I like to think of them as: something you forgot; something you lost, and; something you were!
We will take a look at the current state of authentication, examine weaknesses in authentication factors, introduce the fourth factor of authentication and consider some solutions.
- Overview of authentication methods.
- Why do we have problems with passwords?
- What authentication solutions are there?
