Two-factor authentication adds an extra layer of security by requiring not only a password and username but also something that only the user has on them, such as a piece of information only they should know or have immediately to hand - such as a physical token. This makes it much harder for potential intruders to gain access to an account, thereby helping to prevent unauthorized access.
