Show HN: Made a game to play “5-in-a-row wins tic-tac-toe”. Your turn

Going to play with myself :D https://anvaka.github.io/go-mo-ku/?w=15&h=15&s=XO&l=5&m=33_3...

After someone wins, it's possible to continue playing, but additional 5-in-a-row are not counted.

It is possible to add a minimal password system? Something silly as a 2 digits numbers, so people don't play in the wrong turn by mistake.
