Patent attributes
In one aspect, a device includes a processor and storage accessible to the processor. The storage includes instructions executable by the processor to present, on a display and in virtual space, at least first and second three-dimensional (3D) objects to which user input is directable in a particular sequence to provide a passcode associated with the device. The instructions are also executable to identify receipt of the passcode based on detection of first user input directed in the particular sequence to the first and second 3D objects. The instructions are then executable to authenticate a user responsive to the identification. In various examples, the virtual space may form part of an augmented reality presentation, a mixed reality presentation, and/or a virtual reality presentation.
