Two-Factor Authentication: A security measure that requires a user to provide two different types of credentials to verify their identity before they can access a system or data. This typically involves a combination of something the user knows (like a password), something the user has (like a physical token or a smartphone app), or something the user is (like a biometric characteristic).
