Passphrase
Build a memorable passphrase from short common words joined by hyphens, finished with a two-digit number. Words are far easier to remember and type than a mangled password, and every word you add multiplies how many guesses an attacker needs. The tool prints the actual strength in bits alongside each phrase, with the arithmetic, so you can judge whether it is enough for what you are protecting rather than trusting a colour-coded bar.

💡 Good to know: Four random common words give ~44 bits of entropy — stronger than most 8-character passwords, and actually memorable.

Frequently asked
Why words instead of random characters?
A string of real words is far easier to recall and type accurately, and length is what makes guessing expensive. The trade-off is that each word is drawn from a fixed list, so a word carries less strength than several random characters would.
How many words should I use?
The tool prints the bit figure for whatever you pick, so use that rather than a rule of thumb. As a guide: more words for anything an attacker could attack offline, such as an encrypted file or a password manager; fewer is defensible for an ordinary account that locks out after failed attempts.
How strong is this really?
The number printed with each phrase is the honest one, derived from the size of the word list this tool actually uses. It is deliberately not dressed up. If you need strength beyond what more words can give you comfortably, use the random password generator and store the result in a password manager.
