First of all, I've become somewhat fond of the multiple words passphrase concept over long string of random characters. For a summary of this concept, I invite you to check out this XKCD comic. Short version... individual words are very poor at being random. Changing letters to numbers adds just a TINY amount of randomness. Mixing upper and lower case is just a tiny amount of added randomness. Addiing one punctuation character adds just a tiny amount of randomness. Add it all toether, you have an easy PW to brute-force, but something that is difficult for humans to remember.
HOWEVER, a bunch of unrelated words picked randomly...now that's a huge amount of randomness AND the human brain will often connect words together in ways that will make them memerable without being easy for a computer to guess, at least if you use randomly selected words from a big word list.
Which is what I did here. This is pulling from a list of 235971 words. Zero effort to filter the words has been made -- there will be offensive, inappropriate, and trigger words in this list. No appologies, if you don't like one of these, pick another. Or better yet, mix words between suggestions.
For many sites, you might need to add a capitalized letter or a punctuation character, just follow the requirements of your environment.
Do understand your environment. More recently than I'd like to hope, I found I was using a complicated password in an environment that truncated PWs after eight characters. My complicated password was pretty good, but the first eight characters were trivial, the rest were ignored. oops!
