Come on mate, internet in Australia is pretty shit after the NBN fiasco. Let me know when any of those those 100gbps lines reach 1gbps xD.

For 6 characters is 5 seconds. I like the idea of using passphrases that mix casing with symbols but still they look like like real words, it make easier to write them down when you need them and they can be very long, so they are quite secure, of course using a password manager to be able to manage them.
