Strong and Two-factor Authentication

In the majority of cases, authentication consists of a user name and a password, i.e. is the individual who he/she claims to be?!


Two-factor authentication provides improved security - it requires the user to meet two authentication criteria: a user name/password combination and a token or certificate, known as something you have, something you know


Two-factor authentication offers a more secure approach than a simple static username and password.  Via the security token/certificate, the password typically changes every 30 seconds; so even if it becomes known, it quickly becomes useless.


Strong authentication is a form of computer security in which the identities of networked users, clients and servers are verified without transmitting passwords over the network.
