I went old school
I printed numbers, letters and symbols on a sheet of paper.
About 1/4 inch square
Then, cut all those alphanumerics into separate pieces
Places all pieces of paper into an old pill bottle
When a password is needed, I shake out 15 to 20 pieces. Volia
Then I scroll through the births, 'til I find somebody I recognize, then use their DOB and name as the PW, separated by the "special characters" needed for that particular app. So for example when I got to Wikipedia for December 4, I see that Pappy Boyington was born on this day in 1912, so if I needed a PW for something today I might choose
P#Boyington#12#4#1912
That gets me a combination of characters, capitals, lower cases and numbers that for me is relatively easy to remember because I'll remember the historical figure and if need be, can go look up his/her DOB as needed.
Also, if I have some services I use that require PW updates every 6 months or year, and doing this reminds me of when the changes will be coming up.
