Great so now people need to be rich enough to own multiple phones? Really. The solution can’t be “buy multiple devices” when the average person can barely afford to maintain one working device.
Your computer can also be a passkey.
I currently use both my laptop and my computer as a passkey, and a USB drive. So I have 3 backups to my Google account.
It is true that you do need to be rich enough to own a phone and ~100 USD of something else (laptop or USB), which does put redundancy out of the reach of a large portion of the world. But then they can just use regular 2fa at the expense of not being phishing-proof.
Yes, but in order to add new items to each piece of hardware you have to be physically co-located with all the pieces of hardware you want to use as your backups. Which means they cannot be geographically distributed (or if they are that there is a period of time in which you aren't fully backed up). Which means you're either in a place where you can loose all your keys (e. g. a house fire or a flood) or your in a place where you can loose all the devices that have a key.
You have to be within several layers of bubbles to not see how small a percent of the general population are going to even understand any of this BS.
Things being this complicated makes them a non-starter. A nerd vanity project.
And this isn’t a knock on the “intelligence” of the general population. They quite rightfully won’t want to spend their limited time on God’s earth learning about all this.
