This weekend just gone by I pulled together a quick micro-website to generate easily memorable yet strong passwords.
You're given 4 random words, picked from a set which are all easily visualizable in your imagination. You then use the mnemonic method to make a silly mental image linking the words of your passphrase together.
It turns out that using a password or passphrase like this is more secure but yet easier for you to remember than what websites typically tell you to do in terms of choosing passwords.
Anyway: check it out and hope you find it useful! If you do, share it by "liking" it on Facebook or Tweeting / +1 it.
