The need to come up with a 70+ password was a big barrier to entry for me. I strung all of the traditional passwords I ever used in my life with a recipe for generating a pretty pattern on a Rubik's cube. Adding three additional characters brought me to 70 characters. Ironically, I never key it, but placed it to a KeyPass vault, and simply copy and paste the passphrase.
I've taken to taking something unique to myself, say an old term paper or such, generating a SHA-256 string of it, and use that for a strong password for personal banking or forum passwords. With the news that Yahoo passwords may be compromised, I systematically changed every access password I ever used to the longest password allowed following this procedure.
Here's an interesting exercise, the null passphrase account is 3791936988034107349. This is the "account" opened on simply pressing return for the secret phrase. It owns two aliases, "acountzero", and "zzzz". Surprisingly, there is much activity to this account, about 56 transactions totaling over 143 kNXT. Most of these are transfer in, immediate transfer out. I would suppose that sending to this account is equivalent to leaving a quarter by the payphone. For fun, I sent 1 NXT to it, which you may claim if you wish. When you get it, post your experience here....
