$20 for one in a bundle? Why is it so expensive? I get a 4-core 1.3GHz 1GB RAM SBC I can run desktop and all the crypto in the world on, incl. shipping from China for less than the price of a single U2F knob.
I'd pay $2-3 max per piece. Especially since you need more than a few in order not to cause yourself more trouble than this is worth (to someone who already uses random unique passwords and emails for services).
- yayana 8y agoThe goal is really nonclonable key storage with a minimal CPU and purpose specific firmware, i.e. a sim card. The USB u2fs are about $10 which is pretty reasonable for a newish card with ECC algorithms.
- megous 8y agoWhy is it a goal though? I don't care. U2F to me is useful for protecting from stolen credentials on the web. These attackers will never have physical access to my u2f device to clone it. If you fear people getting physical access to your u2f, they can simply use it if they also know the password. No need for cloning. And if they don't know the password, it's still useless. From that attacker's perspective, your security was reduced to password only. Which is still good, if you take care of your passwords.
