Whatever happened to imagination?
There are unlimited easily remembered algorithms no one is ever going to guess, mine are not necessarily easily remembered by you - but you get the idea...:
1) Add your birth weight in kilos to your age at the millennium in months, ignore the decimal points - insert the first 8 digits after the first 8 letters of the name of your hero... or dog, or spouse, or favorite spaghetti sauce...
2) Allocate the numbers 1-10 to the first 10 words of your favorite quotation. Take the sum of each group of 5 words, add your Gregorian birthday in day/month/year format, and add together to get single digits which themselves represent a word, insert the digits in the words they represent (1st 2nd or 3rd position etc...) for extra security translate the words into French/Hungarian etc....
3) Take the telephone number of the apartment your first lover lived in - mix it with registration number of your first car, birthday of your second wife, and the number of tiles on your bathroom wall....
4) Take the number of electrical outlets in your house/apartment - multiply by your age in leap years, take the first 4 digits of the resulting number to represent the first four paragraphs of your favorite book - then take the first (or 2nd 3rd etc) word as your pass phrase, but include the digits after every 1st or second letter...
5) Google some random trivia and bookmark it - use the use the fibonacci sequence to generate a pass phrase from the 2nd (3rd etc) para of the bookmark...
I could go on like this all night - nobody needs a password keeper or generator - if you give a shit (and mostly I don't) use a a set of personal significant numbers and words in combination with some favorite easy algorithm (even rot13 is fine if the the foundations are inscrutable)
And remember that your passwords are safe only insofar as you convince powerful folks they are not worth cracking...
