For long secure passwords make up a sentence. Example For RV.Net = My grandmother is 89 years old! This gives me fRV=#211is89ye3! That way you do not need to remember a password. You can use any combination of letters and words, all you need to remember is your key. For example the first number after the = is # charters. The hint "Grandmother's Age in 2014".
My actual long secure passwords are much more complicate and i do not need to remember any except the variable in each sentence which are related to the web page.
