Biometric authentication solutions measure users’ live biological characteristics (such as their facial structures, fingerprints, or typing patterns) to authenticate their identities. These solutions are gradually gaining traction in the business world—and it’s easy to see why.
For one, with 61% of all data breaches involving compromised credentials (Verizon), biometric authentication solutions are a powerful alternative to protecting accounts using insecure passwords—or even as just an added layer of security as part of a multi-factor authentication (MFA) process.
Biometric authentication solutions are also a great way to improve the user experience by offering a more passive, frictionless authentication process.
But there are a range of solutions out there that can vary in capabilities and features quite dramatically. Some offer biometric authentication as a standalone identity and access management solution, while others offer their product to be used as part of an MFA or continuous authentication process; some specialize in physiological biometrics (based on physical features such as facial structure and fingerprints) while others focus on behavioral biometrics (based on behavioral characteristics, such as typing patterns or gait).
So, selecting the right solution for your organization in a sea of options can be overwhelming—not to mention time-consuming. But we’re here to help.
We’ve put together a list of the top biometric authentication solutions for business. Throughout this guide, we’ll take a look at a range of biometric authentication solutions—including both physiological and behavioral biometrics products—and delve into what they do, what features they offer, and who they’re best suited for.

BIO-key PortalGuard

BIO-key is an established identity and access management provider with expertise in biometric authentication as well as biometric hardware technologies, such as fingerprint scanners. In 2020, BIO-key’s acquisition of PistolStar brought PortalGuard into its portfolio, an access management platform that provides seamless single sign-on and flexible MFA authentication. The platform enables users to authenticate their identities in various ways, including using BIO-key’s trusted passwordless biometric authentication capabilities.
Using PortalGuard, users can log on password-free by replacing passwords with biometric scans, or alternatively leverage biometrics as part of an MFA process. To complement this platform, BIO-key’s recently-launched mobile app MobileAuth uses PalmPositive technology to verify user identity. To authenticate using this technology, users must scan the palms of their hands using their device’s camera. The app then analyzes the scan on the server rather than on the device, and grants the user access if the scan matches their pre-enrolled biometric template. For admins, the platform also comes with a central dashboard from which they can configure access policies, view real-time activity reports, and more.
Users praise PortalGuard for its smooth implementation, easy two-factor authentication capabilities, and flexibility when integrating with various systems. The platform also integrates with a number of trusted identity and access providers, including Duo, Microsoft Authenticator, Yubico, Authy, and more. We recommend BIO-key’s PortalGuard for organizations in the finance, government, healthcare, and commercial industries that are looking for an established vendor to provide seamless, password-free SSO and MFA capabilities using biometric authentication.
iProov Face Verifier And Palm Verifier

iProov is a biometric authentication provider that specializes in face and palm verification to authenticate users and prevent spoofing. Its Face Verifier and Palm Verifier solutions are built using patented Genuine Presence Assurance technology, which determines whether a user attempting to log in is the right person, a real person, and is authenticating in real-time. Both solutions can also be used as primary authentication, as part of an MFA process, or as step-up authentication.
iProov’s biometric solutions use deep-learning technologies as well as built-in replay-attack and spoof prevention to provide the highest level of security and accuracy during authentication attempts. To authenticate via Face Verifier or Palm Verifier, users must present their faces or palms to their front-facing camera. The technology then compares this authentication attempt to that user’s pre-enrolled biometric template, granting access only if it matches. iProov’s iPortal also provides security teams a centralized reporting area where they can monitor and manage user administration, provisioning, integrations, and more.
The Face Verifier and Palm Verifier solutions are cloud-based and can be used across all devices that have front-facing cameras—making them incredibly scalable and flexible across a range of use cases. Integrating the solutions with existing technologies is also simple, with many organizations finding their integration processes quick and easy to complete. Trusted by public sector organizations, governments, and banks to securely and accurately verify user identity, we recommend iProov’s advanced biometric authentication solutions for large enterprises that need a high level of assurance that users accessing their systems are authorized to do so.
Prove GaitAuth And MotionAuth

Prove is an innovative identity and access management provider that specializes in verifying user identities using just their smartphones. Previously focusing exclusively on authenticating users by connecting to their device’s mobile network, Prove’s 2021 acquisition of UnifyID brought behavioral biometric authentication into its solution. Its newly launched behavioral biometric mobile SDKs GaitAuth and MotionAuth can now be used alongside its phone-centric technology to provide a more seamless and secure login process for users.
Prove’s biometric solutions work silently in the background, passively and continuously authenticating users without the need for them to interact with their devices when authenticating. GaitAuth works by identifying users based on the unique way that they walk, while MotionAuth verifies users based on their motions and behaviors, such as how they interact with devices, their habits, and other contextual factors. Combining phone-centric ID with behavioral biometrics enables users to prove that they are in possession of the device at that time, are associated with the phone number registered to the device, and have had that phone number for a significant length of time.
Prove is rated highly by users as a sophisticated, reliable product that’s easy to set up and provides a smooth, frictionless experience for users. Prove is a particularly popular vendor for financial services organizations, with a client base of more than 500 banks. We recommend Prove for large enterprises in industries such as financial services, healthcare, insurance, and e-commerce that are looking for a passive, frictionless, and secure way of verifying user identity using just a smartphone.
TypingDNA Verify 2FA And ActiveLock

Launched in 2016, TypingDNA is a behavioral biometric authentication vendor that specializes in verifying users based on the way that they type. Its solutions work by leveraging data engineering and deep learning algorithms to analyze typing behaviors and patterns to recognize and verify users in seconds. Using this technology, TypingDNA offers a two-factor authentication product, Verify 2FA, as well as a continuous authentication solution, ActiveLock.
To initially register to use TypingDNA’s products, users need only to provide one typing sample. From this sample, the system analyzes their typing behaviors and can then use this data to recognize them during future authentication attempts. Verify 2FA works by asking users to type only four words into the system to verify their identities. If their typing pattern matches their profile, they’re granted access in seconds. If it doesn’t, but the user happens to be genuine, they can access their account via an SMS-based one-time passcode. ActiveLock, on the other hand, works in the background, monitoring typing behavior as users go about their day and continuously authenticating them. If it detects a typing pattern that doesn’t match the user that registered, it can automatically lock the device or trigger a silent alert.
TypingDNA’s biometric authentication solutions work across all keyboards and devices, and are easy to roll out to users. Verify 2FA also integrates with identity and access providers such as Okta, Keycloak, and Active Directory. Users find TypingDNA’s solutions powerful, responsive, easy to use, and frictionless. We recommend Verify 2FA and ActiveLock for businesses across all industries—especially finance, education, and retail—that are looking for a seamless solution that can not only verify the right users, but also identify when the wrong ones use a device they aren’t authorized to use.
Veridas Voice Authentication

Jointly founded by BBVA and Das-Nano in 2017, Veridas is a biometric authentication vendor that develops face and voice recognition software for businesses globally. Veridas Voice Authentication is its voice recognition solution, which is based on its das-Peak speaker verification engine and can authenticate user identity using less than three seconds of audio.
Users can sign up for the service using just a three-second voice recording. From this, the das-Peak engine uses AI to measure the unique physical characteristics in their voices, such as accent and speed. The system then creates a biometric “vector”, which is a mathematical descriptor of that user’s characteristics and can be used to compare future authentication attempts with. Because the engine only measures characteristics, it doesn’t take into account the context of their words, so users can say anything they want—and, in any language—to verify their identities. The system can also detect hacking attempts that use pre-recorded voices and easily thwart replay attacks.
Veridas Voice Authentication is an easy-to-use cloud-based solution that claims a 99.5% accuracy for its voice recognition technology. Users praise the product for its accuracy, high-quality user experience, flexibility for multiple use cases, and high levels of support when needed. We recommend Veridas Voice Authentication for large enterprises—particularly in telecommunications, banking, and insurance—that are looking for a passive, easy-to-use voice authentication solution that can accurately verify user identity in seconds.
Frequently Asked Questions (FAQs)
How does biometric authentication work?
Most biometric authentication solutions work in a similar way—they require both a pre-enrolled biometric template and fresh data to authenticate a given user. Let’s use facial recognition software as an example.
When a user signs up to use facial recognition software, they must perform an initial scan of their face. This scan is then analyzed and processed by the software, and becomes the biometric template to which all future authentication attempts will be compared.
When a user then attempts to log in using facial recognition software, their new scan is compared to their template—if it matches closely enough, they’re granted access. If it doesn’t, they’re denied.
But facial recognition is a physiological modality—behavioral biometrics work slightly differently. This is because they’re based on a set of recorded behaviors as opposed to a static reading.
For behavioral biometrics, the template is constantly shifting and evolving because the software continuously monitors users in the background. But they still work in the same way in that any new authentication attempt is compared to the template of user behavior in the system.
What’s the difference between physiological and behavioral biometrics?
The two broad categories of biometric characteristics are:
- Physiological biometrics: These are based on physical characteristics such as facial structures, fingerprints, hand geometries, iris patterns, and more.
- Behavioral biometrics: These are based on behavioral characteristics such as typing patterns, gait, mouse tractions, physical movements, and more.
While both types of biometric authentication are incredibly accurate and secure, behavioral biometrics are generally considered slightly stronger than physiological biometrics.
This is because behavioral traits are far harder to spoof, and because they’re based on biometric templates that continuously evolve and grow more accurate as time goes on.
