The Adaptive Authentication Service offers the ability to add multiple steps to the authentication process.
Additional security may be enforced by adding a OTP step, or an Access Request (Push) Notification step after initial user authentication. This may or may not involve the use of the Oracle Mobile Authenticator, a mobile device app that uses Time-based One Time Password and push notifications to authenticate users within the second factor authentication scheme.
Installing Oracle Adaptive Access Manager is not required since the Adaptive Authentication Service uses a set of libraries that makes a OTP step feasible using the Oracle Mobile Authenticator.
The Adaptive Authentication Service has to be licensed and explicitly enabled in order to use it. Once the proper product license is procured you can enable the Adaptive Authentication Service using the Oracle Access Management Console. From the Oracle Access Management Console, the Adaptive Authentication Service can be enabled or disabled from the Available Services link on the Configuration Launch Pad.
