  4. A security dialog opens on your device and asks where to save your passkey.


    Options displayed vary depending on your browser and device operating system. If the device where you started the registration process supports passkeys, you'll be asked to save the passkey to that device. Select Use another device or More options to display additional ways for you to save the passkey.
