Two Factor Authentication

A Glossary

Two Factor Authentication

Two-factor authentication (2FA) is a security process that adds an extra layer of authentication to access a system or application. It requires the user to provide two different factors to prove their identity, such as a password and a verification code sent to their mobile phone. In managed IT services, 2FA is an important security measure to protect against unauthorized access to sensitive data and systems.

By requiring two different forms of authentication, it makes it much more difficult for attackers to gain access to an account, even if they manage to steal the user’s password. 2FA can be implemented using a variety of methods, including text messages, phone calls, mobile apps, physical tokens, and biometric factors such as fingerprints or facial recognition. In many cases, it is a relatively easy and inexpensive way to significantly improve the security of an organization’s systems and data.

We have been using Quikteks as our IT support team for many years. They have always been responsive, polite, thorough and professional. Their techs are all personable and speak to us in language we can understand. I recommend them to any business owner that wants to spend time on his business and leave the IT to the pro's.
