Abstract

This disclosure is directed for improved techniques for configuring a device to generate a secondary password based at least in part on a secure authentication key. The techniques of this disclosure may, in some examples, provide for capturing, by a computing device, an image of a display of another computing device. The captured image includes at least one encoded graphical image, such as a barcode, that includes an indication of the content of a secure authentication key. The computing device may use the secure authentication key to generate a secondary password to be used in conjunction with a primary password to gain access to a password-protected web service.
