jackg, thanks. Yes but from what I could understand, it's more important to have a long password than special characters. It's better to remember a long sentence (a uncommon sentence, just jibberish).
The difficulty will be incremental by every added character, it's easier to remember a long sentence, the password example I gave is a 88 char password. It will take a couple of quadragintillion years to crack.
No, that is incorrect. Long does not necessarily mean secure. Password crackers are not stupid, they aren't going to just brute force your password one character at a time; they are going to use dictionaries, lists of previous passwords, sentences and phrases from common books, etc. Humans are predictable and password crackers use that predictability in order to better crack passwords. While your password is probably secure, it can be cracked much much sooner than the majority of password cracking calculation sites tell you.
