S3 Authentication Suite

Addressing a wide variety of authentication use cases

S3 Authentication Suite

Authentication is the “front door” to digital services. The Nok Nok™ S3 Authentication Suite (the S3 Suite) provides state-of-the-art passwordless authentication that is more convenient and user friendly than passwords or other legacy authentication methods, and at the same time protects against phishing and other attacks.


The S3 Suite addresses a wide variety of authentication use cases:

  • Frictionless on-boarding and progressive profiling, easy cross-device use, account recovery, suspension, and deprovisioning of users.
  • Passwordless authentication support for Desktop Web, Mobile Web, Mobile Apps, Smartwatch Apps and integration for authenticating to call centers.
  • Authentication to cloud services and, in combination with the Nok Nok IoT SDK, to IoT devices.
Complete Protection

Delight Users with Effortless Authentication

Asking users for a new password at sign-up adds unnecessary friction. Forgotten passwords create frustration, and the Nok Nok S3 Suite makes strong passwordless authentication practical, making it easy to migrate from passwords to passkeys.  Passkeys work with any device and reduce friction at sign-up and at sign-in – providing an omnichannel frictionless experience.

Unique Technologies

Strong Multi-Factor Security

Whether you are in a highly regulated industry or concerned about fraud prevention and protecting users and your brand, multi-factor authentication is your first line of defense.


Passwords and OTPs can be phished – one of the dominating attack vectors at this time.  The Nok Nok S3 Suite supports phishing-resistant FIDO passkey-based authentication.  These strong multi-factor authentication methods can be used to authenticate customers, partners and employees.  


With Nok Nok, you get the benefits of strong passwordless security, a frictionless user experience and an authentication process trusted by Fortune 500 companies, and that also helps organizations meet FFIEC, PSD2 SCA, NIST and HIPAA requirements.

Reduce Complexity

Easy No-Code/Low-Code Integration

The Nok Nok S3 Suite’s Plugins for Access Management and support for OIDC allows low-code integrations with your existing IAM and CIAM stack.  It can be integrated with a multiple of such systems at the same time.


Nok Nok App SDKs and Sign-in Widget make it easy to add passwordless authentication to your native apps and web apps, and leverage the authenticators on any device through a single developer API – abstracting away the platform differences and reducing implementation complexity.


The Nok Nok S3 Authentication Suite is easy to integrate with systems that provide additional contextual information, such as external risk engines and behavioral biometric systems.


The flexible platform within the Nok Nok S3 Suite allows for integrating remote identity proofing engines and supports multiple account recovery options.

Easy Configuration

Adaptive Authentication

Nok Nok’s powerful adaptive policy engine allows you to easily configure authentication rulesets that dynamically respond to context. This capability is typically required when following a Continuous Adaptive Risk and Trust Assessment (CARTA) approach or when implementing PSD2 SCA.


By using the Nok Nok S3 Suite adaptive policies combined with strong signals generated by the Nok Nok App SDKs, contextual information provided by business applications and 3rd party risk signals, you can (i) avoid additional authentication prompts, (ii) trigger authentication sequences, or (iii) deny access.

Industry Leading

Proven, Scalable Platform

Authentication is a critical function requiring high availability and zero-downtime upgrades. With years of experience and deep domain expertise, Nok Nok delivers a proven, scalable and future-proof authentication solution. Nok Nok is deployed at scale to major global brands around the world – supporting industry leading mobile network operators and banks, each with tens of millions of customers.


As an inventor of FIDO standards and a founder of the FIDO Alliance, the Nok Nok platform was the first authentication suite to be commercially deployed using FIDO authentication protocols in 2014.


With the S3 Suite’s multi-tenancy support you can authenticate multiple segregated user groups from a single platform for operational efficiency. Additionally, the Nok Nok S3 Suite can be operated in stateless containers, for modern DevOps environments with continuous integration/testing and release automation practices.

Protections for Customer Privacy

Compliance Ready

CCPA and GDPR, and other global regulations, require protections for customer privacy. Utilizing a privacy-by-design approach, the S3 Suite helps organizations avoid the need for storing biometric customer data for authentication purposes, enabling customers to comply with these privacy regulations. In addition, the Nok Nok S3 Suite provides strong multi-factor and user-friendly authentication enabling compliance with FFIEC, PSD2 SCA, NIST and HIPAA requirements. The S3 Suite also supports transaction confirmation and secure payment confirmation (SPC) for approving financial transactions and has feature support for delegated authentication specified by EMVCo 3DS2.
