Passwords suck, but they are the best that we have at the moment in terms of being cheap and free from infrastructure - see

We've been in a bubble for the past few years, where Moore's law hardware had not quite caught up with the speed of SHA and MD5 password hashing throughput for effective brute force guessing; that bubble is well and truly burst.

Welcome back to 1995 where the advice is to change your passwords frequently, because it has a half-life of usefulness imposed upon it from (a) day to day external exposure and (b) the march of technology - and keep your hashing algorithms up to date, too.  See for suggestions.

Have a nice weekend,
