Two-factor authentication (also known as 2FA) is a method for confirming the claimed identity of a user using a combination of two different components. Two-factor authentication is a multi-factor authentication type. A good example of daily life is the withdrawal of money from an ATM; Only the correct combination of a bank card (something that the user owns) and a PIN (personal identification number, something the user knows) allows the transaction to take place.
Two-factor authentication (2FA), often referred to as two-step verification, is a security process in which the user provides two authentication factors to verify who they are who they claim to be. 2FA can be contrasted with single-factor authentication (SFA), a security process in which the user provides only one factor, usually a password. Two-factor authentication provides an additional layer of security and makes it difficult for attackers to access a person's Devices and online accounts, because knowing the victim's password alone is not enough to pass the authentication verification. Two-factor authentication has been used for a long time to control access to sensitive systems and data, and online services are increasingly introducing 2FA to prevent their users' data from being accessed by hackers who have stolen a database Of password data or used phishing campaigns to obtain passwords from users.
