What is 2FA?
“2FA” is an abbreviation for “Two-Factor Authentication”, which is sometimes referred to as Multi-Factor Authentication (MFA). This process provides added electronic security by requiring users to provide two or more verification forms to log in to a website or application.
More About 2FA
2FA helps protect user data and prevent identity theft or fraud online. The evidence required for authentication can be based on knowledge, possession, location, or something inherent to the user (such as voice or fingerprint). Typically, the first form of authentication is a user password, biometric factor, or physical object (such as a debit card). Secondary factors often require users to enter contact information and receive a verification code. This code can be sent via text message, email, or phone call. These verification codes often expire within minutes. Many websites use 2FA software for their security needs. Furthermore, users are usually required to opt-in to this extra layer of protection.
