Our vision is to enable any organization to secure streamlined and passwordless workforce, customer, citizen and student access to any online service, workstation, or mobile application, without a requirement to use tokens or phones for roving users and shared workstations. Our products include PortalGuard® and PortalGuard Identity-as-a-Service (IDaaS) enterprise IAM, WEB-key® biometric civil and large-scale ID infrastructure, MobileAuth® mobile phone authentication application for iOS and Android, and high-quality, low-cost accessory fingerprint scanner and FIDO-compliant hardware to provide a full and complete solution for identity-innovating customers.

BIO-key PortalGuard empowers organizations to maximize the power of cloud, mobile and web technologies by securing users’ identities and connecting them with the applications they rely on, while keeping cyber-intruders and unauthorized delegates (proxy users) out. Competing MFA solutions require a phone or token for every user authentication use case,
