What do you mean by two-factor authentication? |
|
Answer» Two-factor authentication (2FA), often known as two-step verification or dual-factor authentication, is a security method in which users validate their identity using two INDEPENDENT authentication factors. This PROCEDURE is carried out in order to better protect the user's credentials as well as the resources that the user has access to. Single-factor authentication (SFA), in which the user gives only one factor — generally a password or PASSCODE — provides a lower level of security than two-factor authentication (TFA). Since possessing the defendant's password alone is not enough to accomplish the authentication check, two-factor authentication adds an extra layer of security to the authentication PROCESS, making it more DIFFICULT for attackers to get access to a person's devices or online accounts. |
