	Double-factor authentication is a type of multi-factor authentication. 2FA is a technology that provides user identification using a combination of two different components. The bright example of two-factor authentication is [[wikipedia:Google\|Google]] authorization.

	It is important here that the subject has some kind of unique object. It can be a personal seal, a key to the lock, a data file containing a characteristic. The characteristic is often embedded in a special device: for example, a plastic card. It is more difficult for an attacker to get hold of such a device than to crack a password, and the subject can immediately report in case of theft of the device. This makes this method more secure than a password mechanism, but the cost of such a data access protection system is higher.		It is important here that the subject has some kind of unique object.

2FA / Multi-factor authentication

Multi-factor authentication is an extended verification procedure (or a method of controlling access to a computer). To gain access to information, the user must present more than one “proof”.

'''The categories of such evidence include:'''

''Data that the subject possesses.''

This is secret information that only an authorized subject knows. The password can be a speech word, a text word, a combination for a lock or a personal identification number (PIN code.). However, it has significant drawbacks: it is often difficult to keep a password secret, because attackers are constantly coming up with new ways of stealing, hacking and password selection. This makes the password mechanism unsecure. Many secret questions, such as “Where were you born?”, are elementary examples of the knowledge factor, because they can be known to a wide group of people or be investigated.
