Passkey - Disable authentication with another device

[BartekMilew]

I would ask about opportunity to disable and avoid opportunity for user to authenticate with another device.
I encounter information "Sign in with another device" during authentication process and I want to prevent it from appearing. Is it possible ? If not it will be propose to implement. I see that there is option during registration only with attachment-platform

@BartekMilew this sounds like a deployment question, not a spec issue. Please use passkeys.dev/discuss or the FIDO-DEV list.

Deployment question. Nothing actionable for the WebAuthn specification.
