The technology behind Multifactor Authentication
One-Time Passcodes
Both HOTP (HMAC-based One-Time Password) and TOTP (Time-based One-Time Password) approaches rely on standard HMAC-SHA cryptographic functions, ensuring interoperability across platforms and devices. Because the underlying algorithms are open standards, HOTP and TOTP can be integrated into mobile authenticators, hardware tokens and enterprise systems without proprietary lock-in. This flexibility has made them some of the most widely adopted forms of Multifactor Authentication.
In practice, these methods deliver a strong balance of security and usability. Users enter a short numeric code generated by their app or token and the server validates it instantly. This seamless experience, combined with robust cryptographic foundations, ensures organisations benefit from both ease of use and high levels of protection.
Security Tokens
Security tokens are small physical devices that generate one-time codes or connect directly to a computer or mobile device. They provide a straightforward way for users to prove identity, since the token is something they physically carry with them. This adds an extra layer of assurance that cannot be provided by passwords alone.
Because tokens are purpose-built for authentication, they are highly reliable in day-to-day use. They don’t depend on mobile coverage or battery-hungry apps, making them a dependable choice in offices, remote locations and environments where phones are restricted. Their durability and simplicity make them ideal for long-term deployment.
Biometrics
Biometric authentication uses unique physical traits such as fingerprints, facial recognition or voice patterns to confirm identity. These identifiers are highly personal, making them one of the most secure ways to ensure the right person is accessing a system. Unlike passwords, biometrics cannot be forgotten or misplaced, which makes them very convenient.
The technology is now widely available on smartphones, laptops and specialist scanners, meaning most employees already have the tools they need. A simple touch or glance is often enough to log in, which makes the process quick and natural for users. This ease of use helps drive adoption without extra training.

Multifactor Authentication FAQs
Do you still have questions about Multifactor Authentication? We’ve answered the most frequent questions that we’re asked below!
What is Multifactor Authentication?
Multifactor Authentication (MFA) is a method of security that requires a person to provide more than one piece of evidence before gaining access to an account or system. These pieces of evidence, called “factors,” fall into different categories. The most common categories are something you know (like a password), something you have (such as a phone or hardware token) and something you are (biometric features like a fingerprint or face scan). By requiring more than one factor, MFA strengthens access control beyond the protection of a single password.
The purpose of MFA is to make it more difficult for an unauthorised person to log in. Even if a password is guessed or stolen, the attacker would also need the second or third factor to proceed. This extra barrier greatly improves security because each factor is independent. For example, knowing a password does not provide access to someone’s fingerprint or security token.
MFA is widely used across sectors to protect email accounts, online banking, cloud services and workplace systems. It has become a standard recommendation in cybersecurity frameworks, including government and industry guidelines. The forms it takes can vary: one-time passcodes generated by apps, push notifications to a registered phone or hardware keys that connect by USB or NFC. Each of these has the same purpose: to verify that the person logging in is truly the account holder.
In addition to protecting accounts from unauthorised access, MFA supports broader goals like compliance and risk management. Many organisations adopt MFA to meet legal or contractual requirements, especially where sensitive data is involved. Individuals also benefit by having stronger control over their personal accounts. As online threats evolve, MFA remains one of the most effective tools available to strengthen security while keeping login processes practical.
How does Multifactor Authentication work?
Multifactor Authentication (MFA) works by combining different types of identity checks before allowing someone to log in. Each check or “factor,” is chosen from a separate category so that they cannot be easily linked. The most common factors are knowledge (a password or PIN), possession (a mobile device, security key or token) and inherence (a biometric feature such as a fingerprint or face scan). By requiring more than one factor, MFA adds multiple layers of defence to the login process.
When a user attempts to log in, the system first asks for their password. Once entered, it prompts for another factor, such as a code sent to their phone or generated by an app. This code is valid for a short time and changes regularly, making it difficult for attackers to reuse. If the factors provided match what the system expects, access is granted. If one factor fails, the login is blocked.
Behind the scenes, MFA systems use encryption and secure algorithms to generate and check these codes. Standards such as TOTP (Time-based One-Time Password) and FIDO2/WebAuthn provide widely recognised frameworks for how authentication works. These ensure compatibility across different devices and platforms, so businesses and individuals can choose the methods that fit best without sacrificing security.
MFA can also be flexible. Some systems allow risk-based decisions, such as only requesting the second factor when a login seems unusual—for example, from a new device or location. This approach balances security with convenience, so users do not always face extra steps when logging in from trusted devices. In this way, MFA protects accounts while keeping the process practical for everyday use.
Why is Multifactor Authentication important?
Multifactor Authentication (MFA) is important because it greatly reduces the risk of unauthorised access to online accounts and systems. Passwords alone are often weak points in security. They can be guessed, reused across different sites or exposed in data breaches. By requiring additional factors, MFA ensures that a stolen password is not enough on its own to grant access.
The importance of MFA is also linked to how it protects sensitive data. Businesses store financial records, client information and intellectual property in digital systems. Individuals manage personal banking, health information and private communications online. MFA helps secure all of these by adding extra barriers against attackers. Even if one layer is compromised, the others remain in place, making it much harder for unauthorised users to succeed.
MFA is increasingly recognised by governments, industry bodies and regulators as a necessary standard. For example, data protection laws and cybersecurity frameworks often recommend or require MFA for critical accounts. Following these requirements not only strengthens security but also demonstrates compliance and builds trust with customers, clients and partners.
Another reason MFA is important is its adaptability. Organisations and individuals can choose methods that fit their needs, such as biometrics for convenience, hardware tokens for reliability or authenticator apps for mobility. This flexibility allows MFA to be widely adopted without major disruption. Its role in reducing fraud, safeguarding information and supporting compliance has made it one of the most effective measures in modern cybersecurity.
What are examples of Multifactor Authentication?
Multifactor Authentication (MFA) can be applied in several different ways, depending on the type of factors chosen. A common example is the combination of a password and a one-time passcode sent to a mobile phone. In this case, the password represents “something you know,” while the phone provides “something you have.” The user must enter both correctly to gain access, which makes it harder for attackers to break in with just a stolen password.
Another example is the use of biometric authentication. Many devices now support fingerprint or facial recognition as an additional factor. A user might log in with a password and then confirm their identity with a fingerprint scan. This adds the “something you are” category and makes the process quick and user-friendly. It also prevents access if the fingerprint does not match the registered user.
Hardware tokens are also widely used in MFA. These are small physical devices that generate unique codes or connect directly to a computer or mobile device. They are especially popular in industries where security needs to be very high. For instance, some banks provide customers with tokens that create a new code every time they log in, ensuring that each session is uniquely protected.
A further example is push-based authentication, where a user receives a notification on their smartphone after entering their password. They simply approve the request with a tap, confirming that they are the one trying to log in. This method is easy to use and avoids the need to type in codes. Together, these examples show how MFA can be adapted in different ways to suit the security and convenience needs of both individuals and organisations.
How do I set up Multifactor Authentication?
Setting up Multifactor Authentication (MFA) usually begins with enabling it on the account or service you want to protect. Most major platforms—such as email providers, cloud services and banking apps—include MFA options in their security or account settings. Once you switch MFA on, the system will guide you through choosing the second factor alongside your password.
A common setup process involves linking your account to a mobile authenticator app. Apps like Microsoft Authenticator, Google Authenticator or Authy generate time-based one-time passcodes that refresh every 30 seconds. After scanning a QR code or entering a setup key, the app begins creating codes unique to your account. You will then need to enter the code generated on your phone each time you log in.
Other setup options include registering a phone number for SMS or voice calls or pairing a hardware security key with your account. With SMS or calls, you receive a short code each time you attempt to log in. With a security key, you plug in or tap the device to confirm access. Some services also let you set up biometrics if your device supports fingerprint or facial recognition, making login even faster.
As part of the setup, most services encourage users to create backup methods in case the primary factor is unavailable. For example, you might add an extra phone number, generate backup codes to store safely or register more than one device. Taking these steps ensures you can always access your account, even if you lose your phone or token. With these measures in place, MFA is ready to use and provides a much stronger layer of security from the very first login.
