In order to prove the safety and reliability of their products, IT vendors often talk about multi-factor authentication. This feature is presented as one of the key elements in ensuring the security of their offerings. But what exactly is it, and does it really help to protect the sensitive information of your Club? We’ll try to answer all the important questions about MFA in this article.
What is multi-factor authentication?
Multi-factor authentication (MFA) is a method of authentication that requires users to provide two or more pieces of identity evidence to access and log into their accounts. Not just your login and password but something more personal and reliable.
This could include a phone number, email address, or the answer to a (known only to you) secret question. Access to your account is granted only after inputting all the necessary information.
In addition to multi-factor authentication, you may also come across the term two-factor authentication (2FA). The difference is the number of authentication methods. While 2FA typically involves just two methods (usually the first is login+password and the second is SMS, Push notifications, or Time-Based One-Time Password), multi-factor authentication offers a variety of options. With MFA, you can choose from multiple authentication methods based on your preferences.
What factors can be used?
Since it’s termed multi-factor authentication, you’d want to know the types of factors that can be used for identifying. There are five of them.
Knowledge Factor
The knowledge factor confirms identity by requesting information known only to the individual user. Common examples are passwords, PINs, passphrases, and answers to security questions.
Possession Factor
Possession factors confirm identity by requiring proof of information only the user should possess, such as a smart card, a mobile phone, or a token.
Inherence Factor
Inherence factors check identity using unique user features. Fingerprint scanning is a common method since fingerprints are unique. Other factors include voice, handprints, and face recognition.
Location Factor
Location factors confirm identity based on where the user is. If a user signed up in one country but there are login attempts from another, location factors kick in to verify the new user. Many use the IP address to compare the original and new attempts.
Time Factor
Time factors check identity by looking at when access attempts happen. It assumes certain actions should occur at specific times. If someone tries to access outside these times (for example, not during you workday), they might need to prove their identity or be blocked.
How does the MFA work?
Instead of just using the traditional “ID + password” method, MFA asks users to provide extra information to make sure they’re really who they claim to be.
The user’s details are then checked by a central identity provider (IdP) or directory services platform. Once confirmed, the user gets access to what they asked for. In most MFA systems, you get a special one-time passcode (OTP) each time you log in.
Here’s how a usual MFA process works:
Registration
You link something you own, like a phone or a key fob, to the system, confirming it’s yours.
Login
You enter your username and password into a secure system.
Verification
The system checks with the registered item. For phones, you might get a code; for key fobs, a light might go on. Also, if you log in from a computer, you may receive a call on your mobile phone or a request to open a specific app on your phone. For verification, FaceID, TouchID, or voice recognition can be used. In summary, any of the additional factors we described in the previous section can be employed.
Reaction
You finish the process by using the verified item. This could mean entering a code or pressing a button on a key fob.
Some systems ask for this verification every time you log in, while others remember your devices. If you always use the same phone or computer, you might not need to verify each time. But if you try to log in from a new device or at an unusual time, you might need to do the verification step.
Why is multi-factor authentication important?
Users can sometimes make security mistakes by picking weak passwords, using the same password for many things, keeping passwords where others can see them, or keeping the same password for a long time. Multi-factor authentication helps guard against these mistakes.
MFA is a crucial part of Zero Trust security (which means nobody is automatically trusted, whether inside or outside the network. Everyone has to prove their identity to access network resources).
Even if hackers get a user’s password through things like phishing, MFA makes it really hard for them to get the second verification step.
Multi-factor authentication also helps to prevent fraud as it ensures that you are who you claim to be before allowing you to proceed. This extra check becomes an additional layer of security and keeps unauthorized users out of your website and other resources.
Implementing MFA not only strengthens access security for organizations but also ensures compliance with data regulations such as PCI DSS, GDPR, NIST 800-63B, SOX, and HIPAA.
Are there cons of MFA?
There are no actual cons of MFA, except that it is time-consuming. However, safety is more important than the convenience of logging in faster. Also, sometimes, if you misplace the device with the second authentication code, even authorized users might get locked out. Plus, it can cost a bit to set up.
But all these cons are tiny in comparison to the benefits multi-factor authentication offers. Using MFA can prevent many security problems and is really crucial for your Club safety.
