Passphrase Generator Online

Updated 2026-08-19

Generate memorable passphrases online in your browser from random real words. Choose how many words, the separator, and whether to capitalize or add a number, and SnapTools produces a strong passphrase you can copy instantly. Nothing is uploaded — words are selected locally from the BIP39 wordlist, so the secret never leaves your machine.

That privacy guarantee matters for any secret you generate: a passphrase that is transmitted or logged is no longer fully yours. A handful of random words is both easy to remember and hard to guess, making this a strong choice for master passwords, disk encryption, or Wi-Fi keys.

// how to use

  1. 1 Set how many words the passphrase should contain.
  2. 2 Choose the separator between words and whether to capitalize or add a number.
  3. 3 Click Generate to produce a passphrase, then click Copy to use it; refresh for a new one.

// faq

Is the passphrase sent anywhere?
No. Words are selected in your browser and the passphrase never leaves your machine. As with any secret, generating locally means it is not transmitted or logged, so it stays yours alone.
Where do the words come from?
They are drawn at random from the BIP39 wordlist, a curated set of common, distinct words chosen so they are easy to read and type.
How random are the passphrases?
Each word is selected independently from your browser's cryptographic random source, so a four- or five-word passphrase has enough entropy to resist guessing.
What is the difference between this and a password generator?
A password generator produces a dense string of random characters that is hard to memorize. This produces several real words that are far easier to remember and type while still being strong.
How many words should I use?
Four words is a reasonable minimum; five or six gives more strength for high-value accounts. Longer passphrases are stronger and still readable.
