In what ways does two-factor authentication improve security, and how does it work to protect accounts?
Two-factor authentication enhances security by requiring users to provide two forms of verification before granting access to an account. This approach significantly reduces the risk of unauthorized access even if passwords are compromised. The first factor is usually something the user knows, like a password, while the second factor is often something the user possesses, such as a smartphone for receiving a unique code. By combining these two factors, two-factor authentication creates an additional layer of security, making it harder for attackers to gain access to accounts.
