What is Multi-Factor Authentication (MFA)?

Multi-Factor Authentication (MFA, 3FA) adds an extra layer of security to your account, ensuring it’s really you when you log in. Instead of just entering your password, the system might ask for additional proof, such as a one-time code sent to your phone via MFA app, chatbot, push notification, SMS, or email. Or, you may need to answer a secret question, scan your fingerprint, or use the face ID feature.

This robust defense helps protect users’ accounts against cyber attacks and tricky situations where passwords might be at risk. Multi-factor authentication guards against phishing, man-in-the-middle attacks, brute force, and other password-related threats.

Multi-Factor Authentication is also referred to as two-factor authentication, 2-factor authentication, or 2FA. This is because, typically, a combination of two authentication factors is used during login to enhance user-friendliness.

2. Factors of Multi-Factor Authentication

Multi-factor authentication enhances security by requiring a combination of different authentication factors.

Currently, three main types of authentication factors are recognized:

1. Something you know: This includes passwords, usernames, or responses to secret questions like the name of your cat or your favorite author.
2. Something you have: A one-time code generated on your smartphone through an MFA app or received via SMS, chatbot in a messaging app, or email. Or, it can be a special device for one-time password generation called hardware OTP token. It resembles a key fob, USB drive, card, or calculator with a small 6 or 8-digit screen.
3. Something you are: Biometric data, such as fingerprint or retina scans, as well as face ID.

Some security specialists mention a potential fourth factor - the user’s environment. Yet, there is ongoing debate about whether it’s appropriate to classify the user’s environment as a distinct factor. Nevertheless, within the realm of multi-factor authentication, we can delineate two additional factors:

1. 4. Location Verification: Location-based authentication validates a user’s identity by considering their geographical location. For example, if an account registered in one country encounters login attempts from another location, the system, employing geographic and IP filters, will restrict access to the account.
2. 5. Time-Based Authentication: This factor verifies a user’s identity by evaluating the timing of access attempts. It operates on the assumption that specific activities, such as logging into a work computer, typically occur within predictable time ranges. If an access attempt deviates from the expected timeframe, the system will deny access to the account.

3. How Multi-Factor Authentication Works

Signing into your account with just a username and password may seem simple, but it opens the door for anyone with this information to access your account from anywhere globally. This is where Multi-Factor Authentication (MFA) steps in to add an extra layer of security.

The success of multi-factor authentication lies in the strategic combination of various authentication factors, each compensating for the weaknesses of the other. This makes it tough for attackers since compromising all factors at once within a limited time is challenging. Even if one factor is compromised, the account stays secure, providing robust protection.

When MFA is enabled, the authentication process becomes more intriguing.

1. The first step is the usual username and password routine (something you know).
2. Then, you encounter the second factor—a unique identity verification step, which may be:
   • Something you have: a one-time code generated on your smartphone through an MFA app or received via SMS, etc.
   • Something you are: a fingerprint or face ID.
3. Let’s say you choose the Protectimus Smart authenticator app as your second factor. Opening the MFA app on your smartphone reveals a dynamically generated 6-digit number. Inputting this number into the site grants you access.

Now, if someone attempts to log in as you, they hit a roadblock. Even if they know your username and password, they’re stuck at the second factor. Without your smartphone, they can’t obtain the changing 6-digit code. This code, refreshed every 30 seconds, ensures security, even if they somehow knew yesterday’s code.

Breakdown of the MFA process:

1. Registration: Users create an account with a username and password, linking additional items such as a cell phone, physical hardware fob, or virtual items like an email address or mobile number. Biometric information, like fingerprints, can also be added for enhanced security.
2. Authentication: MFA-enabled users logging into a website input their username and password (the first factor) and are prompted to enter one-time codes or perform other actions from their MFA device (the second factor).
3. Reaction: Users complete the authentication by entering a one-time code, pressing a button on a hardware device, scanning their fingerprint, or clicking on the push notification.

4. The Significance of Multi-Factor Authentication

As organizations transition into the digital age and take on greater responsibility for safeguarding customer data, the need for robust security measures, including the adoption of multi-factor authentication (MFA), becomes apparent.

Relying on usernames and passwords, prove unreliable and susceptible to exploitation. Users often struggle to manage credentials, leaving them vulnerable to hacking.

MFA is a vital solution, adding an extra layer of verification to online accounts and reducing the risk of unauthorized access due to compromised passwords. Multi-factor authentication protects accounts from phishing, man-in-the-middle attacks, brute force attempts, credential stuffing, keyloggers, and other password-related attacks.

Certifications and compliance mandates emphasize the importance of MFA. It plays a crucial role in meeting stringent requirements like PCI-DSS, PSD2, GDPR, NIST, FFIEC, NYDFS, NAIC, and other security standards. For businesses and organizations dealing with confidential data, financial transactions, or personal user information, implementing MFA is particularly crucial.

In essence, MFA strengthens digital security, aligns with industry standards, and provides a resilient defense against evolving cyber threats. It stands as an indispensable component in the ongoing battle against digital risks.
