23 Two Factor Authentication (2FA) | Multi-Factor Authentication (MFA) | Linux Networking

What is Multi-Factor Authentication (MFA). What is Two-Factor Authentication. Step by step implementation of Two Factor Authentication (2FA). What are different factors involved in authentication. What do you mean by something you know, something you have and something you are.

Two-Factor Authentication (2FA) and Multi-Factor Authentication (MFA) are two methods of authentication that are commonly used to provide an extra layer of security for user accounts and systems. In this video, we will explore the concepts of 2FA and MFA, their advantages, and how they can be implemented.

Firstly, we will discuss the basics of authentication, including traditional password-based authentication, and the limitations of this method. We will then introduce the concept of 2FA and MFA, which require users to provide additional forms of authentication besides passwords, such as physical tokens or one-time codes sent to registered email or mobile phone numbers. We will explain the differences between 2FA and MFA, including the number of factors required and the types of factors that can be used.

Next, we will discuss the advantages of 2FA and MFA, including protection against password-based attacks such as brute-force attacks, phishing, and social engineering. We will also provide examples of how 2FA and MFA are used in real-world scenarios, including online banking, email accounts, and corporate networks.

Finally, we will provide a step-by-step guide on how to set up and use 2FA and MFA, including configuring systems and services to accept additional forms of authentication, registering physical tokens or mobile devices, and using one-time codes to authenticate.

By the end of this video, you will have a clear understanding of Two-Factor Authentication (2FA) and Multi-Factor Authentication (MFA), their advantages, and how to set them up and use them for secure authentication.
