  Mind that we made one-time pads (like TAN sheets) pretty much a thing of the past, in favor of 2FA…

    If one reads the linked Wikipedia entry, one would learn that OTP is the only uncrackable form of encryption. It’s not something a government can easily block nor decrypt regardless of technology.

      However, for whatever reasons, we have decided that OTPs (as in TANs) are insecure. (Hint: 2FA is much easier and less costly to administrate.)

        Good grief. How is OTP unsafe?
