Methods and systems for implementing keyboard linked authentication challenges are described. A visual representation of a first string of characters is provided for display on a client computing device. In response to the providing the visual representation for display, several keystrokes on the client computing device that produces a second string of characters are received. A determination that the second string of characters matches the first string of characters is made. A determination that no unauthorized keystrokes are included in the detected plurality of keystrokes is further made. Access is provided to the client computing device upon determining that the second string of characters matches the first string of characters, and determining that no unauthorized keystrokes are included in the detected plurality of keystrokes.
