A passkey must be available to the device or password manager you are using and belongs to the Console origin where it was registered. Opening another host or using a different device setup does not make the same credential available automatically.
Open the normal Console address and check your device's passkey provider. Use another sign-in method offered for your account if the passkey is unavailable. Register a replacement only while signed in to the correct account. If the browser reports an error, send support the browser, operating system, and visible message. Do not export or share private passkey material.
