These tasks show you how to use the platform APIs to perform common MFA actions for non-native applications. MFA use cases often call the following platform API resources:

Platform API	Description
Sign-On Policies	Sign-on policies determine the account authentication flow users must complete to access applications secured by PingOne services.
Resources	Resources are the protected endpoints that applications request access to using OAuth 2 authorization services.
Applications	Application resources define the connection between PingOne and the actual application.

Note: Some of the workflows in this section use SMS for multi-factor authentication. For new environments, the environment’s device authentication policy disables SMS and voice devices by default. To enable SMS and voice, see Device Authentication Policy.
