I created a tic tac toe game that allows the user to sign up, log in, log out, change password, and see a display of games played, in addition to playing tic tac toe.
User story -- the user first signs up for a profile, then signs in. A game starts. The user plays tic-tac-toe. They can then sign out or change their password if they so desire.
This game was made with html, css, a small contribution from bootstrap, javascript, jquery, and ajax from communication with the api.
