Random Passphrase Generator
Create strong yet memorable passphrases by stringing together several random common words, in the spirit of the diceware method. A handful of unrelated everyday words is far easier for a human to remember than a jumble of symbols, yet the sheer number of possible combinations makes a well chosen passphrase genuinely hard to guess. Pick how many words you want, choose a separator such as a hyphen, a space or a dot, and optionally sprinkle in a number or capitalize each word for sites that demand it. The words are chosen using your browser secure random source, so the result is truly unpredictable. Everything is generated locally in your browser, so the passphrase you create is never transmitted or stored anywhere. Copy it straight into your password manager.

Frequently asked questions
Why use a passphrase instead of a password?
A passphrase of several random common words is easier to remember yet still high in entropy, so it is both memorable and strong.
Can I change the word count and separator?
Yes. You adjust how many words to use and the separator between them, which lets you tune length and readability.
How are the words chosen?
Words are picked using the cryptographic random source in a diceware style, so the selection is unpredictable and not based on a pattern.
