Zero-Click Auth For Your Apps

Picture this: you've built an arcade game on Replit. Gamers playing your game will head to the repl's cover page and click "Run". They love your game, and they send you feature requests and ideas in the comments. Now, you want to keep track of high scores and add other social features to your game.
