Nok Nok Labs has made FIDO certified multi-factor authentication – which seeks to eliminate dependence on password-based security - available across all digital channels by adding a software development kit (SDK) for smart watches to the latest version of its digital authentication platform, the Nok Nok S3 Authentication Suite.

In truth, the SDK is only for the Apple watchOS, but it is the first - and currently only - SDK available to do all the heavy lifting for developers seeking to enable FIDO-certified authentication via smart watches that do not natively support FIDO, and is a logical starting point due to Apple’s strong position in the smart watch market (just over 50%), with SDKs for other smart watch operating systems expected to follow.

This means that business to consumer organizations can now use the Nok Nok S3 Authentication Suite to enable strong, FIDO-based authentication and access policy controls for Apple Watch apps as well as mobile apps, mobile web and desktop web applications.

The new SDK, like its companion SDKs from Nok Nok, provides a comprehensive set of libraries and application program interfaces (APIs) for software developers to enable FIDO certified multi-factor authentication that uses public and private key pairs, making it resistant to man-in-the-middle attacks because the private key never leaves the authenticator, or in this case, the smart watch.

As global smart watch sales continue to grow, the devices are becoming an increasingly important channel for digital engagement, particularly with 24 to 35-year-olds. At the same time, smart watch usage has grown beyond fitness applications to include banking, productivity apps such as Slack, ecommerce such as Apple Pay, and home security such as NEST.

A further driver for the use of smart watch applications is the fact that consumers often find it easier to access information on a watch without the need for passwords or one-time passcodes, especially smart watches like the Apple Watch that does not rely on having a smartphone nearby.

The move is a strategic one for Nok Nok because it not only satisfies customer requirements, but also fulfils one of the key goals for Nok Nok as a company and the FIDO Alliance as a whole.

From the point of view of S3 Authentication Suite end-user organizations, the new SDK will make it easier to make applications available to consumers on smart watches as a new client platform in its own right and meet the security and privacy requirements of both smart watch users and global, regional and industry-specific regulations, especially in highly-regulated industries such as telecommunications and financial services.

In addition, the SDK for smart watches enables end-user organisations an opportunity to simplify their backend infrastructure by having a single authentication method for all digital channels enabled by a unified backend authentication infrastructure, thereby reducing cost by reducing complexity and operational overhead.

From a Nok Nok point of view, the SDK delivers greater value to existing customers and is likely to win new customers as organisations, particularly in the financial services sector, seek to engage consumers across all available digital channels.

Enabling the same strong FIDO-backed authentication across all digital channels is also a key goal of Nok Nok, both as a company and as a founder member of the FIDO (Fast IDentity Online) Alliance.

The FIDO Alliance is a non-profit consortium of technology industry partners – including Amazon, Facebook, Google, Microsoft and Intel – working to establish standards for strong authentication to address the lack of interoperability among strong authentication devices as well as the problems users face with creating and remembering multiple usernames and passwords.

The FIDO Alliance plans to change the nature of authentication by developing specifications that define an open, scalable, interoperable set of mechanisms that supplant reliance on passwords to securely authenticate users of online services via FIDO-enabled devices.

The new S3 SDK from Nok Nok for Apple watchOS offers a stronger authentication alternative to solutions that typically store OAuth tokens or other bearer tokens in their smart watch applications. These tokens provide relatively weak authentication and need to be renewed frequently because they can be stolen.

In contrast, FIDO-based authenticators provide strong device binding for credentials, providing greater ease of use as well as additional assurance that applications are being accessed only by the smart watch owner (authorized user).

While commercially a strategic move for Nok Nok to be the first mover in enabling strong FIDO-based authentication via its S3 Authentication Suite, the real significance of the new SDK for Apple Watches is that it moves forward the IT industry’s goal of achieving stronger authentication and reducing reliance on password-based security.
