PIN pepper

We need a second device to enforce the time limits

Password security relies to a large degree on the time limits imposed upon password verification.

That is, if I can verify three passwords per minute then guessing an alphanumeric password of eight characters might take approximately Math.pow (36, 8) / 2 / (86400 / 20) / 365 = 2236 years, but if I can verify three million passwords per second then guessing the same password might take Math.pow (36, 8) / 2 / (86400 * 3000000) = 5 days.

If we limit a PIN to be verified no more than three times per ten minutes
