Final answer:
An item such as a physical device required for access to a computer or facility is called a token, and is part of two-factor authentication for security.
Step-by-step explanation:
The item that you must carry to gain access to a computer or computer facility is known as a token. A token can be a physical device, such as a key fob or smart card, that generates a security code used alongside a password to authenticate a user’s identity. These tokens dramatically increase security by adding a second layer of credentials (something you have) to the traditional password (something you know), a strategy known as two-factor authentication.
