Abstract: Examples of a host device that includes an input recess are described. In some examples, the input recess includes a rotating port cover offset from a central axis of the input recess. In some examples, the input recess includes a plurality of contacts disposed on an interfacing surface of the input recess to interface with a print particle replenishment device when the rotating port cover is rotated. In some examples, the plurality of contacts interfaces with a control device to authenticate the print particle replenishment device.
