How easy are you to hack?

Take a quick test and find out the answer!

Cybersecurity is no joke. But still... how well do you actually protect your data? Take the test to discover whether you're an easy target for hackers or perhaps already a stealthy cyber genius. Answer honestly — hackers will find out the truth anyway. 😉

Make a password from random words

A passphrase is a password made of several words. It can be easier to type and remember than a string of mixed characters, especially when you need to enter it without autofill. The words still need to be chosen at random: a favourite quote, a lyric or a sentence about your family is much easier to guess.

This generator picks words from an English dictionary. It creates account passwords, not cryptocurrency wallet recovery phrases.

Choose your settings

  1. Set the number of words. Adding more randomly chosen words gives an attacker more combinations to try. One or two words are a poor choice for an important account.
  2. Choose a word-length range from 2 to 8 letters. Keeping a wider range leaves more words available; choosing only short words reduces the pool.
  3. Select spaces, hyphens, asterisks or commas between words. Check which separators the account accepts.
  4. If the site requires a digit or uppercase letter, enable those options. The digit option adds one digit to each word.
  5. Copy the result and save it in your password manager. Use a different phrase for each account.

The generator uses the browser’s random-number facility to select distinct words. It saves your settings in cookies, not the generated phrase. Refreshing the page creates a new result, so save the one you intend to use before leaving. If the account has a short maximum length, a random character password may fit better.

Why there is no “years to crack” promise

A long word is not a set of independently chosen letters. Treating a word-based password as random characters overstates how many guesses an attacker needs. The number of available words, how they are selected, and how the account stores passwords all matter. A familiar separator or a capital at the start of every word does not replace adding more random words.

A published example is useful for understanding the format, but anyone can copy it. Generate your own phrase instead. Even a well-chosen password cannot prevent every account attack; enable multi-factor authentication where the service supports it. The EFF guide to strong passwords explains random passphrases, password managers and additional account protection.

Is this a 12- or 24-word seed phrase generator?

No. A wallet recovery phrase has a specific format. For example, BIP39 uses a 2048-word list and a checksum, with 12, 15, 18, 21 or 24 words. Selecting that many ordinary words does not make a valid wallet backup. A BIP39 wallet may also support an additional passphrase; that is separate from its recovery words.

Create and restore a wallet through its own documented setup process. Do not paste an existing recovery phrase into this generator or a password checker. Keep it private and follow the instructions for your wallet; Trezor’s backup guide describes the precautions for its devices.
