How can multi-factor authentication enhance email security?

Multi-factor authentication enhances email security by requiring additional verification for access. This method adds layers of security beyond just a username and password. When a user attempts to log in, they are prompted to provide something they know (like a password), along with something they have (like a mobile device to receive a text message or an authentication app). This makes it significantly more difficult for unauthorized users to gain access to an email account, even if they have obtained the password.

The effectiveness of multi-factor authentication lies in the fact that it mitigates the risk of common security threats, such as phishing attacks or password theft. Even if an attacker were to acquire a password, they would still need the second form of authentication, which is typically tied to the legitimate user’s personal device. This added layer ensures that only authorized individuals can access the account, thereby significantly enhancing overall email security.
