Second, the answer to your question is: yes. You can issue your passcode ahead of time to be safe. Just keep it where only you have access to it. WARNING: Issued passcodes only last for a year, not indefinitely. Also, passcodes are one-time use only. So, a year after you've first issued a passcode, assuming you haven't used it yet, you have to issue another one.
