About
A compact sign-in card that lets returning users authenticate with a passkey using Face ID, Touch ID, or a security key, with an option to fall back to a password.
Built with React and Tailwind. Copy the prompt and paste it into Claude Code, Cursor or Lovable: your agent adds Passkey Sign-In to your project and fits it to your theme.
Code
How Passkey Sign-In is used: the demo's code. The component's own source comes with a free account.
