Nok Nok Labs is a passwordless authentication company that develops and deploys FIDO (Fast Identity Online) standards-based authentication solutions for enterprises and service providers. The company's core product, the S3 Authentication Suite, enables organizations to replace traditional password-based authentication with biometric and device-based methods across mobile and web applications. The platform supports a range of authentication modalities including fingerprint, facial recognition, iris scanning, and device-based authenticators, allowing end users to verify their identity without passwords. Nok Nok's solutions are designed to integrate with existing identity infrastructure and comply with FIDO Alliance standards, which are widely adopted in the authentication industry. Nok Nok serves a diverse set of industries including telecommunications, financial services, and government. Notable deployments include T-Mobile, NTT DOCOMO, SoftBank, MUFG Bank, Intuit, BBVA, and Gallagher. The company has also supported government-level use cases, such as delivering an electronic identity (eID) system for the citizens of Liechtenstein in partnership with YOUNIQX Identity AG. The company's platform is used both in consumer-facing applications to reduce friction during authentication flows and in enterprise environments including IoT access control scenarios. Measurable outcomes reported by customers include significant reductions in forgotten password incidents and improvements in user experience. Nok Nok is headquartered in the San Francisco Bay Area and counts DCM Ventures among its investors.
