multifactor authentication

Multifactor authentication (MFA) is a security process that requires you to verify your identity using multiple methods before gaining access to an account or system. Instead of just entering a password, you might need to provide something you know (like a password), something you have (like a smartphone or a security token), or something you are (like a fingerprint or facial recognition). This layered approach makes it much harder for unauthorized people to access your information, because even if one method is compromised, they still need the other factors to get in.
