I like doing entire phrases with some rhymes thrown in. Makes it easier to remember them.
“BonyTonyMoansHe’sOnlyGrownLonely” has a shitload of characters, and a full sentence (even a nonsensical one like that) is more memorable to me than a random handful of disparate words.
The more ridiculous, the better. (And, naturally, don’t forget your numbers and symbols)
EDIT: Actually, no idea why I made it all one group of words. So long as spaces are in the password’s character space (and they very well should be if friggin’ emojis are), there’s nothing stopping you from doing an entire, punctuated sentence- other than that we’ve been conditioned not to think of a password that way.
“Skinny Kenny’s friend, Mini Ben, has 20 chins.” That should be a fully-acceptable password with 46 characters (48 if you add the quotes), capital letters, numbers, and special characters.
