A passphrase made of several random common words can be both easier to remember and harder to crack than a shorter string of random characters, since each additional word multiplies the number of possible combinations.
This generator builds a random passphrase from a fixed wordlist, along with an entropy estimate showing how strong it is.
How it works
Choose how many words you want, a separator character, and whether to append a random number. The generator randomly selects that many words from its wordlist and joins them, then calculates the resulting entropy based on the wordlist size and word count.
- Enter number of words.
- Enter separator.
- Enter include a random number.
- Click Calculate to see your results.
Examples
A 4-word passphrase
Four randomly selected words joined by hyphens (like "kitchen-emerald-comet-ladder") produce a passphrase with roughly 28.5 bits of entropy — easier to type and remember than an equivalent-strength random character string.
Who should use it
- Generating a memorable but strong password for a personal account.
- Creating a passphrase for a password manager's master password.
Industry applications
- Information security and password management
- Personal account security
Advantages
- Produces passphrases that are both strong and easy to remember and type.
- Reports an entropy estimate so you can judge the strength of the result.
Limitations
- Uses a fixed wordlist, so extremely high-security contexts may prefer a larger, specialized Diceware wordlist.
Common mistakes to avoid
- Using too few words, which reduces entropy significantly — a 3-word passphrase is much weaker than a 6-word one.
- Reusing the same generated passphrase across multiple accounts.
Best practices
- Use at least 4-5 words for a genuinely strong passphrase, and use a unique passphrase for each account.
Tips
- Store your generated passphrase in a password manager rather than relying on memory alone, especially if you generate a unique one for every account.
