Change Your Default Verification Method Using the My Profile Console
You can change your default verification method using the My Profile console if you are enrolled in more than one method.
Prerequisite: You must first enable 2-Step Verification. Most users do this when they first log in to Oracle Identity Cloud Service. If your administrator made 2-Step Authentication optional, and you have clicked Skip each time you log in, you can enable 2-Step Authentication in the My Profile console Security tab. See Enroll in 2-Step Verification After First Login.
The check mark appears on the method pane that you just set as your default.
