Why do we use passwords?
Passwords are used in today's digital environment to protect and secure personal accounts.  They are a line of defense against domestic and abroad criminals trying to get access to your personal information in order to steal your identity, open credit cards in your name or steal your hard earned money from your bank accounts.   Password management is hard for a lot of people because they use the same password for every account, they write them down and cannot remember all of them, and have no way to effectively manage their passwords or secure them.
