I use a different password on each of my major accounts.  I have a program
that, given N-1 of the passwords, will output the missing one.  So I'm safe
until I forget two passwords at the same time.

(No, the program itself doesn't know my passwords.  It only knows the XOR of
a base-95 encoding of them.  The source code and data file are readable.)
