Not one that can store an arbitrary number of passkeys that work across different browsers/computers.

I don't think you understand how FIDO2 works.

If you are using non-discoverable keys, the type where you input your username to login and then it asks for the passkey, there is no limit because they are calculated from a single master key and seeded with the url.

If you are using discoverable keys when you don't even input a username to login, the latest Yubikey has a limit of 100 but other vendors hold more.

Physical hardware keys work across most devices and browsers as long as you have the key with you.
