Generate memorable passphrases from random words with customizable word count, separators, and capitalization.
This tool builds a passphrase by drawing a set number of random words from a built-in list and joining them with a separator you choose - hyphen, space, dot, underscore, or none - then applying whichever capitalization rule you pick, such as capitalizing every word, one random word, or leaving everything lowercase. Everything runs in the browser; nothing is sent anywhere. The part people misjudge is where the strength actually comes from: it's the word count and the size of the underlying word list, not the separator character or capitalization pattern, which are mostly cosmetic and add very little extra guessing difficulty compared to one more word.
Each slot in the passphrase is filled by picking one entry independently at random from the tool's word list, repeated for however many words you've set the count to. Because each pick is independent, the same word can in principle appear twice in one passphrase unless the generator specifically checks for and excludes repeats, which this profile can't confirm without inspecting the tool's behavior directly.
Once the words are chosen, the tool joins them using the separator you selected and applies the capitalization mode you picked. These formatting choices change how the passphrase looks and how easy it is to type, but they add only a small, roughly fixed amount to the total number of possible outputs - nowhere near as much as increasing the word count does.
A little, but not much. Appending one digit or symbol only multiplies the guessing space by roughly ten to a few dozen, while adding one more word typically multiplies it by the size of the entire word list, often thousands. If you want a meaningfully stronger passphrase, add a word instead of a suffix character.
That depends on whether the generator draws from a cryptographically secure source, such as the browser's crypto.getRandomValues, rather than Math.random. That's standard practice for security-focused generators, but treat any specific claim about this tool's internals as unverified unless the site documents it.
