The Purdue BoilerKey is a convenient means of significantly improving the security of protected computer systems. Activating BoilerKey is an implementation of two-factor authentication, a system that requires two forms of verification of identity before a person can access protected computer resources -- something that you have and something that you know.

At Purdue, these two forms of verification are something you know (career account and either a password or PIN) and something you have (a BoilerKey token or the Duo Mobile application on your smartphone). These two items are used in place of your password alone to gain access to computer applications and systems.
