FAQ
What is a passkey?
A passkey is a WebAuthn-based credential that replaces passwords, using device biometrics or a PIN plus public-key cryptography instead of a shared secret you type in.
What does this actually check?
It checks whether your current browser and operating system combination supports the WebAuthn APIs that passkeys rely on.
What if my browser isn't supported?
Passkey support has expanded quickly across major browsers — updating to a recent version, or switching browsers, usually resolves it.
