No passwords stored. No accounts created. Just pure cryptographic proof that you control your keys.\r\n\r\nI demo this live with two apps I built\u2014a Substack writing guide and a birthday countdown\u2014showing exactly how challenge-response signing works in practice. You'll see what happens when it succeeds AND when it fails (spoiler: change two characters and it all falls apart \ud83d\udca5).\r\n\r\nThis isn't the whole Web3 stack. It's the primitive that everything else builds on. Your identity - Your keys - Your control.\r\n\r\nhttps://youtu.be/Cq499ZkykZ4?si=d6Z4zRn4rP8vLB0N",
