The point I made is that your keys are only as safe as the login of your account.
So it doesn’t matter if you store your SAFE keys on hardware or not, it is your account credentials that are essential to keep secret. And as far as I can see a hardware password device would/could do this already.
Once logged in to SAFE then all your SAFE keys and coins are accessible.
I am not talking of other crypto coins since we already have hardware for those.
The password device I am checking out has encrypted communications from device to browser and at no time is the password in plain text till the browser has it in memory. A browser addon decrypts the password and then it is send to the website when you log on. In other words the username and password are always encrypted through the entry process. The device requires a pin and 3 wrong in a row melts down the stored passwords in the device.
Hopefully something like this can be incorporated in the sign on for SAFE and since both SAFE and the device is opensourced I am sure the hardware maker can write an addon for the SAFE login (once SAFE has enough use that is)
