What is Two-factor authentication (also known as 2FA) ?
Multi-factor authentication (MFA) is a method of computer access control in which a user is only granted access after successfully presenting several separate pieces of evidence to an authentication mechanism – typically at least two of the following categories: knowledge (something they know), possession (something they have), and inherence (something they are).
Two-factor authentication (also known as 2FA) is a method of confirming a user’s claimed identity by utilizing a combination of two different components. Two-factor authentication is a type of multi-factor authentication.
A good example from everyday life is the withdrawing of money from a cash machine; only the correct combination of a bank card (something that the user possesses) and a PIN (personal identification number, something that the user knows) allows the transaction to be carried out.
