Describe the capabilities of two-factor authentication.
Two-factor authentication refers to requiring two independent mechanisms to successfully authenticate.
The most common example of this is a username/password combined with a randomly generated number or passphrase (similar to computer activation – however, is required for every login).
Two-factor authentication is typically reserved for high-security environments.
