Nebi bas smjelo do takvog scenarija doci (prvi link gore koji sam postao):

Misunderstanding: You can’t sign in to your accounts if you don’t have the device that contains your passkeys

What happens if you arrive at work and realize you’ve forgotten the phone that has all your passkeys? Will you be locked out of all your online accounts? Not necessarily.
Google, Apple, and Microsoft will sync your passkeys across devices using their respective cloud-based storage services. So if you create a passkey using an iPhone, you can access the same passkey on your other Apple devices via iCloud.
Okay, but what happens if you’ve forgotten your iPhone, but need to use a Windows PC in a public library? In this scenario, you should be given a second option to sign in. For example, a website might send you a “magic link” — a one-time link that lets you instantly sign in — to your chosen email address.

...ali da je to jedini nacin authentifikcije - da onda bi bio problem.
