You can passphrase!
How quickly can you memorize the passphrases/passwords below? I hope you find it easier than expected, with some tricks.
Each phrase is formed so that the first letters of each word correspond to the letters in the "seed word" ("article" by default), so think about this word if you get stuck. You could try to create vivid imagery with the words. For example "ant run tictac" could evoke images of an ant running to get a taste of a sugary Tictac mint. It's not "ant tictac run", because "atr" doesn't align with the "art" in article. The seed word is intentionally picked so that no letters are repeated. This allows you to associate the words in any order. If your mental story ends with "aim", you still know it's the first word because it starts with "a".
Try adding ?seedword=abs (or any word) to the URL for some shorter passphrases. Or go crazy with ?seedword=quickyellowrat, or back to ?seedword=article
The default word bank is from the Diceware word list, to which this owes much inspiration.

Note - this site doesn't store your passphrases. (But, how do you know? You shouldn't necessarily trust me, if I'm trying to teach you better security!)
