Any chance you guys can make a Nostr backup key USB drive? I need a USB-stick with fingerprint authentication to decrypt the payload in the USB and reveal a person's private key.
The goal is to easily spread your keys in 2-3 homes/service providers without letting them access the key. This is for backup purposes. If your house burns down, you can go to your friend's house and get the USB stick back to access your Nostr account. More importantly, whoever hosts the USB stick must never have access the key itself.
It needs to be super simple. We plan to give them away to the homeless population to let them access digital services via Nostr. Their personal security is not good and their ability to memorize pins (mental health issues) is limited. So, it must be something based on biometrics.
Something like this, but with your backing in the security and privacy of the systems would be ideal: https://www.lexar.com/product/lexar-jumpdrive-fingerprint-f35-usb-3-0-flash-drive/
