Multi-Factor Authentication Flashcards
What is Multi-Factor Authentication (MFA)?
Multi-Factor Authentication (MFA) is a security model that requires users to provide multiple forms of authentication before accessing a system or account.
What are the key components of the MFA Model?
The MFA Model revolves around something you know, something you have, and/or something you are. Users must authenticate using at least two of these factors to unlock or authenticate their identity.
Can you provide an example of how MFA works?
When logging into a website, after entering the username and password (something you know), a second factor is required for validation. This could be a code from a password authenticator app on your smartphone (something you have), adding an extra layer of security.
How does MFA enhance security for user identities?
MFA ensures that accounts and identities have multiple layers of validation, requiring at least two components from something you know, something you have, and/or something you are. This adds an additional layer of security beyond traditional password authentication.
What is the significance of MFA in modern security practices?
MFA is increasingly becoming the norm as a foundational step in layered security for user identities. It provides enhanced protection against unauthorized access by requiring multiple forms of authentication.
