The verbal passcode to access an alarm account is an important security feature. If you give an incorrect passcode the operator will ask you to verify your code, possibly by spelling it out phonetically. If on the second attempt you give another incorrect code the call will be ended. For safety and security reasons the operator cannot say "that is not the correct code" nor can they give you clues to the correct code. When you call in or receive a call, you must have the correct passcode and/or account number.
