I wrote my Passcode down but lost it before using it. Can someone else use it?
You should never write your Passcodes down. Passcodes should be used immediately after they have been generated. In the event you lose an ‘active’ OTP, you can deactivate it instantly by generating a new OTP and using it immediately. By using the new OTP, you will have rendered the older Passcode obsolete. The use of the newest passcode automatically invalidates use of all previously generated passcodes, even if they have never been used.
