In the recent announcement of Fido Alliance it is stated that 
  1. Allow users to automatically access their FIDO sign-in credentials (referred to by some as a “passkey”) on many of their devices, even new ones, without having to re-enroll every account.
  2. Enable users to use FIDO authentication on their mobile device to sign in to an app or website on a nearby device, regardless of the OS platform or browser they are running.
Does anyone have an idea on how the access on the keys regardless of the OS platform or browser is achieved? More specifically if the keys are stored in the secure element of the device how can they be access from another device? Also how vendors will work together to achieve that?

one possible choice could be a solution that apps that run on TVs often use already where you do the sign in on your other device and just enter a sign in code that identifies the waiting session, or similarly scan a QR code which directs you to a website that does the same.

one other way that could work would be entirely forgoing the idea of the secure element, tho I would not consider that a great idea.
