Using only a username and password to access an application can result in compromised credentials and cause a huge loss to the organization. While users can, and will, be blocked from accessing an application after a certain number of failed login attempts, hackers still have a variety of other methods available to them to gain access to an application, which is why multi-factor authentication is so important.
Multi-factor authentication (MFA) is a security technology that allows a user to log in or perform other transactions only when they complete multiple authentication steps.
MFA creates multiple layers of protection that make it harder for any unauthorized user to access an application. If one layer breaks, the attacker still has to break through one or more barriers to get access, which is not an easy task.
