Overview

Passwordless APIs can be used in two scenarios: 

1. When implementing Universal Login (or) Context-Based MFA, you want the user to log in to Cross Identity without requiring a password. 
2. When you want to embed the login flow in your application. 

Within this document, we will delve into the rationale for adopting a passwordless approach. We will discuss the implementation of an API that triggers the Passwordless authentication flow in Cross Identity using a push notification. Our Passwordless Authentication feature is not limited to our Cross Identity IAM solution alone; it can also be seamlessly integrated into any third-party application that necessitates user authentication, enabling users to authenticate without the need to input credentials.

Once the third-party application is authenticated, it can use the passwordless API to authenticate its own users. For example, if the third-party application provides a service that requires user authentication, it can use the passwordless API to authenticate its users without requiring them to enter a password.
