Authsignal Browser Javascript SDK

Authsignal provides passwordless step up authentication (Multi-factor Authentication - MFA) that can be placed anywhere within your application. Authsignal also provides a no-code fraud risk rules engine to manage when step up challenges are triggered.

Usage

The Authsignal Browser API can be used to launch Authsignal's Challenge UI to let users set up MFA and complete challenges.

See the documentation for details on how to use this SDK with the Authsignal Server APIs.
