Multi-factor authentication is a way to add layers of security to the standard password method of online identification. With the added security of two-factor authentication you would enter your username and password but would also be prompted to enter one additional authentication method such as a Personal Identification Code, another password or even biometric security, such as fingerprint identification.
One-Factor Authentication: This refers to something users may know about. The classic password is a great example.
Two-Factor Authentication: This adds to the previous one and is typically something the user “owns.” This involves the now common Google authenticator, followed by the biometric fingerprint or certificates.
Three-Factor Authentication: Along with the two we have already mentioned, this identifies something peculiar to the user, a “physical trait”. It includes biometric retina scan, and voice recognition.
Several elements are required to access the network include an app on a smartphone, a certificate on a computer that enables connection to the company VPN and a password. This safeguards your data and your digital assets, even if criminals break passwords or use brute force attacks to obtain them, they will find it incredibly hard to log in.
Unlike passwords, certificates are easily revoked. The password can be identified by the hacker, but in the case of certificates, getting into the system can prove to be quite difficult.
