MFA stands for "Multi-Factor Authentication." It is a security process that involves using more than one method to verify the identity of a user. MFA is often used to protect online accounts and systems against unauthorized access.
MFA typically involves the use of two or more factors to authenticate a user's identity. These factors can include something the user knows (such as a password or a PIN), something the user has (such as a security token or a smartphone), or something the user is (such as a fingerprint or a facial recognition).
The use of multiple factors helps to ensure that the user is who they claim to be, because an attacker would need to have access to multiple pieces of information in order to gain access to the system. This makes MFA more secure than traditional single-factor authentication, which only requires a single piece of information (such as a password) to authenticate a user's identity.
MFA is used in a variety of settings, including online banking, online shopping, and corporate IT systems. It is an effective way to protect against identity theft and other forms of cybercrime.
