What is the purpose of Multi-Factor Authentication (MFA) in AWS?

Multi-Factor Authentication (MFA) in AWS serves the critical role of enhancing security by requiring users to present multiple forms of verification before gaining access to their accounts. This typically involves something the user knows (like a password) and something the user has (such as a temporary code generated by an authenticator app or sent via SMS). By implementing this additional step, MFA significantly reduces the risk of unauthorized access, even if a password is compromised.

The primary focus of MFA is not on simplifying the login process or optimizing the user experience, which may be secondary benefits but are not its main purpose. While MFA can contribute to a more secure environment that ultimately allows for a smoother user experience, its foundational goal is to add a robust layer of security. It also does not relate to account creation processes, as MFA is about securing access to existing accounts rather than enabling account creation, be it free or otherwise.
