I use a simple rotating hash prefix in front of a changing base that in some way has something to do with the site I'm logging into.
for years I had:
AndN0W4s0meth1ngC0MPL3T3LYd1ff3r3nt.., followed by something that referred to the site like NYT for the new york times, or whatever..
I use a number of slightly shorter,, and completely different, prefix hashes for my passwords these days

..or, in the case of Beth here, I uhh.., forgot my old pass word, requested a new one, plugged it into firefox, and uhh.., can't remember what it was anymore since I log in automatically with firefox. :facepalm:
I remember it was complicated though :biggrin:
