Multi Factor Authentication

Multi Factor authentication as the name suggests uses an additional factor of authentication to gain access to multiple applications or services. Instead of usual two factor authentication it uses third factor authentication like biometrics (hand fingerprints, face recognition, iris scan etc.) for providing the necessary authentication. MFA stands on three basic criteria - What you know, What you have and What you are. Modern MFA strengthens security. FIDO2 is password less authentication which can foil phishing attacks. As companies move their systems to the cloud they can no longer rely upon a user being physically on the same network as the system has a security factor. Additional security needs to be put into place to ensure that those accessing the systems are genuine actors. As users are accessing these systems anytime and from any place, MFA can help ensure they are whom they say by prompting additional authentication factors. This way it becomes more difficult for hackers to imitate or use brute force attack methods.
