Today we rely on the Internet for almost everything including every conceivable type of account that contains reams of personal information. During the early days of the Internet most people felt it was relatively safe to rely their user name and password to verify credentials and access their accounts. Today many companies are now turning to a two factor authentication system using an RSA token to provide the extra layer of authentication.
An RSA Token Can Be a Physical Device or an Application
An RSA token can be in the form of a key fob device or in many cases an application for your iPhone, Smartphone or other portable device. No matter which device you are using it will provide a constantly changing series of numbers that have a very limited use time. As you go to log into your account you are required to enter your username and password and then you will then be prompted to enter the numbers on your RSA token in order to be granted access to your account.
