If someone steals my phone today, I can still access most of my accounts, and can regain access quickly to the others.
Now let’s assume passkeys are ubiquitous and used to log in to every website.
If they can’t be exported, then your entire digital existence is at the mercy of whatever device or technology platform you use to store your passkeys. If you lose access to the platform, you also permanently lose access to every single account you’ve ever signed up for. For me, that would include losing access to my retirement savings, tax records, and the ability to communicate with many of my friends, to give a few examples.
My computer also doesn’t have Bluetooth, which means I can no longer log in to any websites on it even when I do have access to my passkeys.
