Description

Fixes CORE-4060.

Mosaic was missing the option to use a passkey for the second verification step. This adds it and makes it the first choice when the account and browser support it, just like the old UI. Users can still choose another method.

The screenshots use the same test account setup. Both method menus are opened from the authenticator step.
