The new kind of password I will create is using the bar code scanner to scan the bar code that contains the authentication key for the account. The user needs to have a bar code scanner ready on the side when logging in and scanning the bar code only has 3 attempts, so the user has to make the scanning efficient and accurate. If the password has to be updated a new bar code image will be generated and should be printed and stored safely.
