Can I use my voiceprint on another device?

Yes. Your voiceprint is stored on your account, so enrolling once covers every browser and machine you sign into.

This is the one part of voice that follows you. The print is saved against your user account rather than to the browser, and it is loaded when you sign in elsewhere. Only the fingerprint and its metadata travel — never audio.
