There have been countless cyberbreaches over the past few years in which personal data, such as user IDs and passwords, have been compromised. These range from attacks against government agencies, such as two recent incidents affecting the national identity systems in Spain and Estonia, to corporate breaches exposing data belonging to millions of customers.

In the aftermath of many of these incidents, affected organizations have been forced to prompt their customers to change their passwords. Many experts and major industry players have even called for organizations to cease using password protection altogether.
