1. A method comprising:

  • detecting, by a motion detector on a secured device, motion during entry of first access credentials by a user on a keypad on the secured device, the first access credentials selected from the group consisting of a personal identification number (PIN), a code and a password, wherein the motion detector is separate from the keypad and detects motion resulting from the entry of the first access credentials via the keypad;

    storing first motion data in association with the first access credentials, the first motion data indicating a pattern of the detected motion and of a cadence of the detected motion;

    granting access to a secured feature of the secured device upon receiving user access credentials matching the first access credentials accompanied by detected motion that produces user motion data matching the first motion data to a degree within a defined valid data range of the first motion data;

    requiring a first re-entry of the user access credentials when the user motion data differs from the first motion data to a degree greater than the valid data range but less than a first threshold range that is larger than the valid data range;

    denying the user access to the secured feature when the first re-entry results in motion data that falls outside of a second threshold range that is larger than the valid data range and smaller than the first threshold range; and

    allowing the user access to the secured feature when the first re-entry results in motion data that falls inside of the second threshold range.
