Two-factor authentication (alternatively 2-factor authentication or 2FA) is a security method that requires users to provide two types of identification before gaining access to an account or system. Typically, this includes something you know (like a password) and something you have (like a smartphone or hardware token). It adds an extra layer of security to protect against unauthorized access.
