What is the proper procedure to allow users to reset their passkey

What is the best practice for allowing users to reset a passkey (WebAuthn)?

Should I just have them click a link in their email like it was a password, or is there a more secure way of doing it? In addition, is there best practice way of allowing users to login to a new device without a synced passkey.
