> You still have to remember what it is that you signed. Unless you are saying it is a challenge/response thing. In which case you have to know what public key they have. You say that like it is a problem? Like I said, you could easily and securely get away with a single private key, so there isn't really any guesswork here. Certainly remembering usernames for hundreds of sites would be worse. And if you want a different key pair for your porn, you can do that and it is on you to remember which one to use, same as usernames and passwords. > a compromised private key is complete game over Yeah, just like a compromised password manager is. Can't really do much about that.
