BIO-key MobileAuth

BIO-key MobileAuth delivers secure, easy-to-use mobile authentication powered by the local biometrics on users’ smartphones. It works with BIO-key PortalGuard and third-party platforms to enable defense-grade authentication for your entire user base, all from the app in the palm of your hand.

“BIO-key provided us with an easy way to implement two-factor authentication while maintaining roaming profiles for our users.”

Jennifer J. Edwards, Network Security Specialist, Collier County Supervisor of Elections

“It prevented us from losing millions of dollars in lost revenue due to the new MFA requirements placed on dealerships like ours.”

IT Director, Krumland Auto Group

“When it comes to authentication, these experts know what they are doing.”

BIO-key MobileAuth capabilities

Verify the user
not the device

Identity-bound biometrics verify who the actual user is, not just device ownership.

Red icon: fingerprint

Add advanced

MFA

Enables passwordless MFA via push notifications and advanced biometrics.

Red icon: hand

Multi-biometrics support

Includes face, fingerprint and palm scanning, all via the user’s own Apple or Android smartphone.

Use cases

Man at the airport with luggage bad and laptop on his lap listening to something with earphone

A mobile workforce takes laptops into client and other third-party environments in which you don’t have full control.

Challenge

Find a way to prevent unauthorized access to these systems with high levels of security but without slowing down your users.

Outcome

With BIO-key MobileAuth, users can authenticate themselves quickly and securely, even when they can’t connect to MobileAuth servers.

Man and a woman looking at a tablet smiling in front of a cladded wall

Customers need an easy but compliant and secure means to authenticate themselves for services that use sensitive information.

Challenge

Finding a means of ID that does not require third-party devices, is easy to use and is secure.

Outcome

BIO-key MobileAuth enables customers to securely authenticate themselves with their own devices, quickly and easily.

An organization with a zero-trust environment needs a stronger form of identification to ensure that the authentication process isn’t a point of weakness.

Challenge

Finding an authentication method that is robust and integrates with the policy-defined zero-trust environment.

Outcome

BIO-key MobileAuth integrates with a range of zero-trust implementations to work as primary or step-up authentication.

A company needs a robust layer of technology-enabled protection against phishing, to underpin its user-awareness training and human-centered protection efforts.

Challenge

To make password theft impossible or of little or no use to cyber criminals without adding complexity for users.

Outcome

Criminals cannot easily steal or clone user biometrics but legitimate users can log in quickly and easily with BIO-key MobileAuth.

Integrations

Customer benefits

With BIO-key MobileAuth organizations can:

Red icon: server hard drives

Combine locally accessed, centrally stored biometrics for convenience and security.

Red icon: declining chart

Reduce capital expenditure and minimize enrollment overheads by using already owned devices to authenticate. 

Improve employee and customer experience with fast biometric authentication on familiar devices.

Bind authentication to one verified user only - unlike device biometrics that allow multiple users.

Combine locally accessed, centrally stored biometrics for convenience and security.

BIO-key case studies

Monash Health

Customized authentication for 14,000 healthcare users

Monash Health, a major Australian healthcare provider, needed a secure, HIPAA-compliant authentication solution to replace aging 2FA software and reduce password-related help desk calls.

Challenge

With over 3,000 password-related IT support calls per month, Monash Health required a scalable, customizable login solution for Outlook Web App and internal systems — without compromising regulatory compliance.

Outcome

Using BIO-key’s PortalGuard, Monash Health implemented secure 2FA and self-service password reset across devices and apps. The solution reduced help desk calls and improved compliance and user experience.

Frequently asked questions

To activate MobileAuth, download the app from the App Store or Google Play. During your first login to a PortalGuard- or WEB-key-enabled system, you’ll be prompted to scan a QR code to link your device. Once paired, you can authenticate using push notifications, biometrics, or device-based passkeys.

Yes. For security reasons, biometric data is stored only on your device and is never transmitted or stored in the cloud. If you lose or replace your phone, you’ll need to re-enroll your biometrics on the new device. PortalGuard provides self-service recovery options or IT-assisted re-enrollment to restore access quickly and securely.

MobileAuth is designed to be flexible. If your device lacks biometric sensors, you can still authenticate using other supported methods such as:

  • Push notifications
  • PIN or passcode
  • FIDO2/WebAuthn tokens (if enabled by your organization)

This ensures that users without biometric-capable devices can still access systems securely.

MobileAuth uses identity-bound biometrics and device-based cryptographic keys to ensure that authentication is tied to the individual user and their device. It supports FIDO2/WebAuthn standards, which eliminate shared secrets and are resistant to phishing attacks. Biometric spoofing is mitigated by relying on the device’s secure enclave and native biometric protections (e.g., liveness detection).

Yes. PortalGuard and MobileAuth support adaptive authentication policies, allowing organizations to assign different methods based on user roles, device types, or contextual risk factors. For example, high-risk users may be required to use biometrics and push approval, while others may use OTP or PIN-based methods.
