I use passkeys and find them great, mind you I know that you need at least 2 of them so you have a backup. I also use yubikeys at work and they are the same issue, you need 2 of them in case 1 breaks or gets lost.
Maybe the setup should be, make sure you have 2 passkeys on 2 different devices? but not in your password manager
I think you can make a template from the helpers page, see if that works
