> So, no online banking of any sort, because if your account number and passwords became public, that would be bad? No use of credit cards for the same reason? No, I do use secrecy there. Defaulting to public is compatible with having a few specific small pieces of information secret (passwords, the pattern on my house keys, the numbers on my credit cards). I don't expect these to remain private long term, for the same reasons I've said above, so we'll eventually need to move away from these as the attacks get cheaper and easier. I already use securitykeys on my most important accounts, credit cards are switching to chips when possible, RFID keys are replacing traditional ones etc; this process is already in progress.
