MFA Meaning: What is Multi-Factor Authentication?

At IT Support companies such as Managed IT Services Miami we will help you implement MFA.  While 2FA is the most common form of MFA, other types of MFA use different combinations of factors. For example, some systems might require a password and a fingerprint, while others might use a password and a question that only you would know the answer to.

MFA is an important security measure because it makes it much harder for attackers to gain access to your online accounts. Even if they manage to steal your password, they’ll still need your second factor to log in

Difference between MFA and Two-Factor Authentication (2FA)

MFA and 2FA are often used interchangeably, but there is a subtle difference between the two terms.
MFA is a general term that refers to any system that uses two or more factors to verify your identity. 2FA, on the other hand, specifically refers to systems that use a password and a code from a physical or virtual device.
While 2FA is the most common form of MFA, other types of MFA use different combinations of factors. For example, some systems might require a password and a fingerprint, while others might use a password and a question that only you would know the answer to.

Authentication vs. Authorization

It’s important to understand the difference between authentication and authorization.

Authentication is the process of verifying your identity. This is typically done by providing a username and password, but can also be done with other methods like fingerprints or iris scanning.

Authorization, on the other hand, is the process of determining whether or not you have access to a particular resource. For example, even if you have successfully authenticated yourself, you might not be authorized to view certain sensitive information.

In short, authentication is used to verify who you are, while authorization is used to determine what you can do.

MFA vs. Single Sign-On (SSO)

Another common security term you might come across is single sign-on (SSO). While SSO and MFA are both authentication methods, they serve different purposes.

SSO is a system that allows you to use one set of credentials (usually a username and password) to access multiple applications. This is convenient because you don’t have to remember multiple sets of login information, but it also comes with some security risks.

If an attacker manages to steal your SSO credentials, they will be able to access all of the applications that use those credentials. For this reason, many organizations require MFA for sensitive applications, even if they use SSO for other less critical applications.

How to Simplify MFA?

There are a few different ways you can make MFA simpler and less time-consuming.

One option is to use a password manager like LastPass or 1Password. These tools can generate and store codes for you, so you don’t have to remember them.

Another option is to use an authenticator app like Authy or Google Authenticator. These apps can generate codes for you on your smartphone, so you don’t need to carry a physical device with you.

You can also try using a service like Microsoft Azure Multi-Factor Authentication or Okta Verify. These services provide an extra layer of security and can be used with applications that don’t natively support MFA.
