Most password advice boils down to "use more characters and more symbols" — sound advice, and also
the reason so many people end up with a password they can't actually remember and have to reset every
few weeks. A passphrase takes a different route to the same strength: instead of packing
randomness into a short string of mixed characters, it spreads that randomness across several whole
words. The result is longer to type but, done properly, considerably easier to recall.
- Length beats complexity once you're past a basic threshold of character variety — a longer phrase of ordinary words can out-resist a short, symbol-heavy password.
- A classic diceware generator draws each word independently from a huge, unrestricted wordlist — the "correct horse battery staple" approach.
- A funny-sentence passphrase trades a little entropy per word for a vivid, memorable mini-story — useful, but only if the generator is honest about the trade-off.
- Whichever style you use, generate it somewhere that runs entirely in your browser and never sends the result anywhere.
Why a random passphrase generator beats a character-soup password
A brute-force attacker has to search through every possible combination until they hit yours. What
matters for that search space is entropy — measured in bits, it's the number of times the number of
guesses doubles before your secret is found on average. Two things drive entropy up: how many
possible symbols could appear at each position, and how many positions there are.
Character-random passwords lean on the first lever: mixing uppercase, lowercase, digits, and symbols
widens the pool of possible characters at each slot. Passphrases lean on the second: instead of one
character per slot, each "slot" is an entire word drawn from a wordlist of thousands. Six words drawn
independently from a 7,776-word list carry roughly 77–78 bits of entropy — solidly in the "strong"
band — while being nothing more exotic to type than six ordinary words in a row.
"Correct horse battery staple": the diceware idea, explained
The phrase "correct horse battery staple" comes from a widely shared webcomic making exactly this
point: a short, symbol-heavy password can be weaker than a few unrelated words strung together,
despite looking scarier to type. The technique behind it — diceware — is simple and auditable:
roll dice (or, online, use a cryptographically secure random number generator) to pick words
independently from a fixed, public wordlist, then join them together. The EFF's long wordlist
(7,776 words, public domain) is the standard choice, and it's exactly what a proper diceware
generator should be drawing from — not a smaller, "curated for vibes" list that quietly reduces
your entropy without telling you.
The strength of a diceware passphrase is easy to check yourself: multiply your word count by
log2(wordlist size). Six words from the 7,776-word EFF list gives roughly 6 × 12.92 ≈
77.5 bits — no black box required.
The trade-off with plain diceware is memorability. Four or six unrelated nouns don't naturally link
together in your head, so you're still rote-memorising an arbitrary sequence — just a sequence of
words instead of characters.
When funny beats plain: the memorability trick
This is where a funny password generator approach earns its place, provided it's honest about
what it's doing. Instead of drawing unrelated words, a grammar-template generator arranges words into
a fixed slot order — adjective, noun, verb, and so on — so the output reads as a tiny, absurd
sentence rather than a word list. "angry-teapot-juggles-purple-donkeys" forms a mental picture in a
way that four random nouns never quite manage, which genuinely helps recall.
The honest catch: each slot in a grammar template is drawn from a smaller, purpose-built list (the
adjective list, the noun list, the verb list) rather than one enormous shared wordlist, so the
entropy per word is usually lower than free-form diceware. A tool that quietly skips over this either
doesn't understand its own maths or doesn't want you to notice. Skojio's Passphrase Generator shows
the exact bit count for whichever mode you're in, plus a standing note whenever the funny-sentence
mode is active, reminding you to switch to Classic Diceware, use the longer template, or add extra
digits and symbols if you need maximum resistance.
Numbers, symbols, and separators — do they matter?
Adding one or two random digits, or a single symbol, contributes a small, disclosed amount of extra
entropy on top of your word-based bits. It's a genuine bonus, but it isn't a substitute for enough
words — three digits add roughly 10 bits, while a single extra six-letter word typically adds far
more. Separators (hyphens, periods, spaces) don't affect entropy at all; pick whichever is easiest to
type on the keyboard or device you'll be using the passphrase with, and avoid a letter-or-digit
separator that could visually blend into the words either side of it. If a site specifically demands
digits and symbols, a passphrase generator with numbers and symbols support (rather than one that
only ever outputs bare words) lets you satisfy that policy without giving up the memorability.
Password vs passphrase: which should you use?
Neither replaces the other — they suit different situations:
- Passphrase: master password for a password manager, Wi-Fi network password, device unlock code, or a recovery phrase you need to recall without writing it down. Anywhere you'll actually type or remember the secret yourself, length-based passphrases are usually the easier win.
- Password: an individual site login you'll only ever paste from a password manager. Here, a short, maximum-entropy, fully random string generated by Skojio's Password Generator is the more familiar, equally strong fit — you never have to type or remember it at all.
Try it yourself
Skojio's Passphrase Generator runs both approaches side by side: a
Funny Sentence mode for something memorable, and a Classic Diceware mode using the full EFF long
wordlist, with one transparent, mode-aware entropy meter for whichever you pick. Everything is
generated using the browser's own cryptographically secure random number generator — nothing you
generate is ever sent to a server, stored, or logged.
Length beats complexity — a passphrase of ordinary words can out-resist a short, symbol-heavy
password, and it's far easier to actually remember.
If you'd rather keep the character-random style for logins you'll always paste from a manager,
Skojio's Password Generator covers that case with the same bulk
generation, export, and honest strength metre.
