Why use Multi-Factor Authentication (MFA)
Multi-Factor Authentication (MFA) is a security system that verifies a user’s identity by requiring multiple credentials. So rather than just requiring a username and password to log on, MFA requires additional credentials such as, a code from the user’s smartphone, a security question answer, a fingerprint, or facial recognition.
Traditional usernames and passwords can be hacked, stolen (or inadvertently given away) and MFA creates multiple layers of security to ensure that the user who is requesting access, is actually who they claim to be. With MFA, even if your username and password are compromised, it’s useless without other information.
MFA gets a bad rap - to most employees it can seem like an annoying extra step with no visible benefit. In reality, MFA is a security shortcut designed to make high-level security easy and once installed it generally simplifies login (most users won't have to enter extra credentials every time if accessing from the same location) and gives enormous peace of mind. Without MFA, you are vulnerable to scams and attacks and being locked out. By using MFA you’re taking a step towards compliance that will support the protection of your sensitive financial, personal or business data.
