Two-factor authentication (2FA), also known as dual-factor authentication or two-step verification, provides the users with a two-step authentication factor for verification purposes. It is a part of the security process. It is done to safeguard the user’s accessible resources and credentials. Under the two-factor authentication process, you need to provide a password and a biometric factor or a security token. This security process offers an additional layer of security against theft of password database or phishing campaigns. There are now various authenticator apps available for 2FA.
