Typing biometrics authentication

Catch fraudsters instantly

Prevent fraudulent users from gaining access as they attempt it. Our API returns an actionable result from the matching engine when you submit typing patterns for verification.

Seamless authentication

Your end-users don’t have to suffer for added protection. Typing biometrics enables frictionless keystroke authentication in the background of any typed text. No need for additional browser permissions and no impact on the UX.

Text characteristics

TypingDNA supports repetitive text (e.g. login authentication credentials) and any text (e.g. writing an email) recognition, so that you can use it in any typing scenario.

Technology

Device and language

Keystroke authentication provided by TypingDNA works on desktops and smartphones. It supports almost all languages as keyboard layouts are similar across different languages.

One enrollment

TypingDNA's unique approach allows you to authenticate a user starting with only one previous enrollment, depending on your plan.

Automated identity verification

No more need for manual identity checks. Verify the identity of millions of users with our automated keystroke dynamics API approach.

Mobile compatibility

Native implementation

Typing biometrics authentication works on Android, iOS, and ReactNative.

Wide-availability

Keyboards are universal which makes typing behavior the most widely available form of biometrics on smartphones.

High accuracy

Comprehensive user profile based on the user's recorded typing pattern and mobile sensor data from user-device interaction.

Frequently asked questions

What is recorded in a typing pattern?

Our main “typing pattern” is an array of numbers utilizing keystroke dynamics statistics regarding the 44 keys that are used most of the time.

Every time we collect a typing pattern (regardless of the number of keys pressed), we get a 320 feature vector.

How unique are the typing patterns?

Any two typing patterns are different, even those from the same individual. In order to perform typing biometrics authentication you need to rely heavily on artificial intelligence/machine learning.

Matching a pattern against others preserving high accuracy, high speed, and low cost is not an easy job.

What about pricing?

We offer flexible, free Developer plan along with Pro and Enterprise options for users with more advanced requirements.
Visit our pricing page, for more info.

How does the API work?

Before authenticating a user, at least 1 previous enrollment (saved typing pattern) must exist (3 enrollments for Developer accounts). Initial enrollments are typically collected and submitted by applications at the time of user account creation.

After enrollment minimums are met, authentications are performed by recording new patterns at log-in attempt (i.e, as credentials are typed). The new patterns are sent to our API to be matched against the previously saved patterns captured from the trusted user during the initial enrollment period.

Our API returns an actionable match result to your application, giving you the information you need to proceed. For more detailed technical information, please see our API documentation.
