Multifactor Authentication (MFA) is a security process that requires users to verify their identity using two or more independent credentials before gaining access to an account or system. These credentials typically fall into categories such as something you know (like a password), something you have (like a smartphone or security token), and something you are (like a fingerprint or facial recognition). By combining multiple authentication factors, MFA significantly reduces the risk of unauthorized access, even if one credential is compromised. MFA is widely used to protect sensitive information in online banking, corporate networks, and personal accounts.
