A user receives a code on their mobile device after entering their password. This step is an example of ____________ in the authentication process.

The described scenario represents Two-Factor Authentication (2FA) where the user combines something they know (password) with something they have (code on mobile device) for enhanced security. 2FA adds an extra layer of protection, reducing the risk of unauthorized access even if passwords are compromised. Recognizing the elements of 2FA is crucial for organizations implementing robust authentication mechanisms.__________________________________________________
