I never understood why this is not for sale. Like for real. 100% privacy? this is much needed.

And just to be clear, the title and all are misleading because what i actually want to suggest is a bit more.

Let's say i have a pc, i start Proton VPN, and it works no issue since the physical key is inserted. But then i want to use this on a different device, well all i need to do is unplug it, put it in another pc, open proton apps, and well, i don't need to write my password. Not for drive, not for email, not for pass, not for vpn, and i am logged in.

Also please be aware that i am not suggesting this for convenience but for security reasons

bonus info: you need at leas 2 of them since each is the single in the world. And if you lose, damage, corrupt, break, gets stolen, you can't access your account, at all. Done. Can't be undone. it's gone. So this is why one is the one you actually use and one that while you register (so it can be used to unlock), it is placed somewhere safe where no one can touch it....???

the other bonus info, the idea of such keys is that they are physically inside, i understand it's like a silicon or something that gets read so it's not a password or otherwise that can be take or stolen.

LAST BONUS!!! Use this keys for a proton account that you don't use for anything other then to take control of you main proton account. Meaning that even if someone steals you physical key, and wants to use it to get access to your main account, it will not work since that key is actually for the master account and, even if someone (room mates, flat mates, house mates, friend, work collage, guest, family, hidden cameras as sadly this is getting worse and worse, so on), see you putting in the usb, that is actually just you faking it. Why faking it? so that they have the impression they can't touch your account without that key so they will not annoy you about it since the key is to special to just borrow <- as a reminder, I am not talking about people who you can trust, but the type who want to know more then you permitted them.

EDIT: sorry for the rand. I am annoyed beyond words how many people want other people's data to scam, sell, or otherwise. And i though me writing like how i wrote it's better then me talking about criminal organisations, ai, and other stuff that are actually worse then what i wrote.
