Remove a 2–Step Verification Method
Use the 2–Step Verification section of the Security tab in Oracle Identity Cloud Service My Profile console to remove a verification method from your account.
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.
