My password evolution seems to be good. Years ago I had simple passwords like "1234567", which are "
Your password would be cracked
Instantly".

Later I started to use more complicated ones like "Mitkoo", but it shows that they weren't better, because "
It would take a computer about
4 hundred milliseconds
to crack your password", which means "nearly instantly".

My best password that time was like "nanarr" which is this "strong": "
It would take a computer about
7 milliseconds
to crack your password". Well, for a person it was nearly impossible to guess it, but for a computer nowadays it's a piece of cake (7 milliseconds! Wow!)
The recent years I improved them like "Difficultone2", which shows a really good result: "
It would take a computer about
1 hundred thousand years
to crack your password". My recent one is like "792Domoarigato" which is also pretty good with this result: "
It would take a computer about
9 million years
to crack your password".

Well, I don't know can we trust 100% this tool (which claims that it is "The #1 Password Strength Tool. Trusted and used by millions."), but if it's really good and real (I hope so), then the conclusion is that the best passwords are sentences without spaces (because they're easy to remember, easy to type and hard to crack) like these two:
- Pandaisananimal ("Panda is an animal.") It would take a computer about 43 million years
to crack this password. - Youarenotahacker ("You are not a hacker.") It would take a computer about 2 billion years
to crack this password.
.
The second best are shorter ones, easy to remember and easy to type and not easy to crack like these two:
- General111111. It would take a computer about 1 hundred thousand years
to crack this password. - 09876Smoothie. It would take a computer about 1 hundred thousand years
to crack this password.
.
The ones often recommended (combinations of small and capital letter with numbers and special symbols) are not that good, especially when they're short. For example these 2 are difficult to guess but easy to crack:
- Ko4@Jp9^. It would take a computer about 8 hours
to crack this password. - Y)t(2%1B. It would take a computer about 8 hours
to crack this password.
.
Only 8 hours, you see? Use this type, if you wish, only when it's longer, like these two:
- 197GHK@%^oK. It would take a computer about 4 hundred years
to crack this password. - K0i!2@zH1wJ. It would take a computer about 4 hundred years
to crack this password.
. I suppose that 400 years is okay. Of course, if add just one more letter, number or symbol it's already okay for sure. For example, "197GHK@%^oK" + "E" = "197GHK@%^oKE" ("It would take a computer about 34 thousand years
to crack your password".) or "K0i!2@zH1wJ" + "7" = "K0i!2@zH1wJ7" ("It would take a computer about 34 thousand years
to crack your password".)
34 000 years = surely okay.

And still, I think the best (one of the best) password should be something like: "Welikesushi1999" (comes from "We like sushi." with a "1999") which gives you this level of security:
It would take a computer about
6 hundred million years
to crack your password
.

600 000 000 years! Cool, isn't it? A similar one: "IloveyouLong2022" (comes from "I love you, Long!" with a "2022") gives you this level of security:
It would take a computer about
37 billion years
to crack your password
.

And, at the end, I can give you an idea how to make one of (probably) the best passwords ever, i. e. a password easy (for you) to remember it, not difficult to type it, when you log in somewhere and very difficult for people to guess it and nearly impossible for the computers to crack it. For example you like carrots, so you can use the word "carrots"; you hate mosquitoes, so you can use the word "mosquitoes" too; your birthday is 20.11.1999, so you can use it twice in your password like "20111999". So, you can have a password like "20111999carrots20111999mosquitoes" (
It takes a computer about 1 decillion years to crack your password).

But, let's say it's too long and/or too complicated for you, so I'll make another suggestion. If you like apples and you hate spiders, you can just make a combination of these 2 words with your favorite number (repeated few times) -- for example, you like "7" and then your best passwords can be: "7Apples77spiders777" ("It takes a computer about 9 quadrillion years
to crack your password".) or if you worry that someone who knows you really well, would guess even this password, you can just change the last three 7s ("777") with another easy to remember combination like "Abc", you'll have then "7Apples77spidersAbc" which also takes about 9 quadrillion years to be cracked.

And okay, for these guys who think that this type of passwords are still "too long" or "too complicated", there is a perfect way to solve their problem. They can just pick up sentences like "We like apples. We don't like elephants." and to use only the first letters of them -- "W li ap W do li el", combine them together and get "WliapWdoliel". It takes a computer about 3 hundred years to crack your password. If you think 300 years is pretty weak, then just add a number somewhere, for example, at the beginning of the password, like this: "3WliapWdoliel". It already takes a computer about 1 hundred thousand years to crack the password. For the most lazy ones, the last example of a very good password: type your name (for example "Chad"), type an easy number like "11223344" and end it with a letter, for example "p". Then you got "Chad11223344p" and it would also take a computer about 1 hundred thousand years to crack your password.
