I haven’t used passkeys yet, but I would hope that you can have multiple keys per site, not just one. So, after going through some initial pain of setting up each individual device, it should be nice having local-only keys for each of them, which you could revoke at any time.
Password managers are also adding support for passkeys, so you should be able to sync them if you so wish.

There are two types of passkey. Syncable and device-bound. (see fidoalliance.org/passkeys/). Theoretically, the device-bound passkeys never leave the device and users don’t have any access to it except to use it for authentication. The syncable type will first and foremost be synced by the platforms themselves (Google, Microsoft, and Apple), but eventually the 3rd-party password managers will be allowed to be sync providers, but possibly only on newly-released OSes.
As far as I know, the passkey implementations currently on Android and Windows are device-bound; they are not synced to the cloud.

Windows currently doesn’t sync, but GMS Android does.
