As a part of {{ site.data.product.shortName }}, the {{ site.data.lib.name }}
allows you to strengthen your web application security with multicactor authentication (MFA) 
seamlesly working with various authentication devices like fingerprint readers, card readers,
cameras for face recognition, FIDO tokens, OTP tokens, as well as with traditional credentials
like password, PIN or security questions.

The library provides API for enrollment of user credentials from a web browser.

## Dependencies

The library depends on 
* DigitalPersona Web Services API
* DigitalPersona Core API

It also requires DigitalPersona Web Components and DigitalPersona Authentication Server

the {{ site.data.lib.shortName }}.
