On: Write your passwords down (2010)

You can just append whatever character requirements they have. So instead of "correcthorsebatterystaple", you can do "CorrectHorseBatteryStaple123!". Should meet most requirements.

Although I just use a password manager but to each their own.

Also, spaces sometimes count as "special character" requirements, so sometimes just "sentence form" passes: "Correct, 1 horse battery staple!"
