No it isn't, because unlike passwords you can reuse a key pair indefinitely without suffering any greater risk. If we only ever had to remember a handful of passwords you would be right about them being easier, but we have hundreds of them which necessitates a password manager anyway which has all the same manageability problems of the asymmetric key pair without any of the benefits. > Auditing is also harder, now Care to elaborate?

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. And if it is challenge/response, you need to have different public keys, or a compromised private key is complete game over, just like a shared password. Thinking on it more, I'm not sure why I think auditing is harder. Is hard regardless, but I don't think this makes it tougher. If you are reusing public keys on N sites, it is now N places to check for use per key. Though, you always had N places to audit. They could be independent without reuse, but still not easy.

  > 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.
