System and method for implementing keyboard linked authentication challenges

A method for enhancing security for log in sessions, the method comprising:

• detecting, in response to a log in prompt, a plurality of keystrokes on a client computing device that produces a first string of characters corresponding to a username and a second string of characters corresponding to a password;
• authenticating the first and second strings of characters;
• determining that no unauthorized keystrokes are included in the plurality of keystrokes based at least in part on keystroke data including a code associated with each keystroke of the plurality of keystrokes, wherein the unauthorized keystrokes include keystrokes not included in an expected combination of keystrokes associated with the first string of characters;
• and
• providing access to the client computing device upon authenticating the first and second strings of characters and determining that no unauthorized keystrokes are included in the plurality of keystrokes.

A non-transitory machine-readable medium having stored thereon machine-readable instructions executable to cause performance of operations comprising:

• providing for display on a client computing device a visual representation of a first string of characters;
• detecting, in response to the providing the visual representation for display, a plurality of keystrokes on the client computing device that produces a second string of characters;
• determining that the second string of characters matches the first string of characters;
• determining that no unauthorized keystrokes are included in the plurality of keystrokes based at least in part on keystroke data including a code associated with each keystroke of the plurality of keystrokes, wherein the unauthorized keystrokes include keystrokes not included in an expected combination of keystrokes associated with the first string of characters;
• and
• providing access 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 plurality of keystrokes.
