Application Level Multifactor Authentication
You can configure multifactor authentication (MFA) at the application level. By adding MFA to an app, you provide an additional layer of security for specific apps. The end users you assign the app to must respond to additional authentication factors to access the app.
You can configure app-level MFA by itself or both org-level MFA and app-level MFA together. Refer to Multifactor Authentication for more information on org-level MFA. If you configure both, your end users are asked for the additional authentication factors when they sign into Okta and again when they sign into apps that you have configured for app-level MFA.
To configure app-level MFA, perform the following steps:
About End-User Sign On
The next time your end users attempt to launch an app that has app-level MFA, they are prompted to set up their extra verification information for the additional factors you configured if they have not already done so. For example, if you configured SMS as an additional factor, end users must provide a mobile number at which they can receive SMS text messages. If they have already configured their extra verification settings, they are only prompted to provide the additional authentication factors to obtain access to the app.
