Some examples include determining a traffic region of a touchscreen prior to presentation of a passcode entry interface based on determining a portion of the touchscreen receiving a number of touch events that exceeds a touch event threshold and/or based on determining a portion of the touchscreen on which was presented another user interface that received one or more touch events immediately prior to the presentation of the passcode entry interface. Based at least partially on the traffic region, a location on the touchscreen may be determined for presenting the passcode entry interface. The passcode entry interface may include buttons corresponding to character options for composing a passcode entry. The passcode entry interface may be presented at the determined location on the touchscreen with at least one of the buttons overlapping the traffic region of the touchscreen.
