Abstract
A login interface provided by a firmware setup utility is configured to display a two-dimensional barcode, such as a quick response ('QR') code. The barcode is scanned by a mobile device configured to retrieve a timestamp encrypted within the barcode. The mobile device creates a passcode by re-encrypting the timestamp using a firmware setup password and a master key. The passcode is provided to the firmware setup utility, which retrieves the timestamp and compares it to a stored timestamp. If the timestamp values match, access to the firmware setup utility is permitted.
