Sign in or create an account before registering a passkey. A connected wallet is not an authenticated account.

Checked live in your browser — these capabilities determine how enrollment will work for you.
A passkey is not quantum-proof.
Passkeys use P-256 elliptic-curve signatures — excellent against phishing and theft today, but vulnerable to a large quantum computer, like Ed25519. p256 never presents them as post-quantum protection.
How enrollment works
Create
Your authenticator generates a P-256 key pair. p256 receives no private keys or biometric data.
Verify
You confirm with Face ID, Touch ID, Windows Hello or your device PIN.
Register
Only the public key is linked to your p256 account, bound to this domain so phishing sites can't use it.
