Random passphrase generator
Generate independently chosen words for a password you need to type or remember. Choose the word count and keep the result in a safe place.
Each word is selected from Passary’s 864-word list. Repeated words are possible. This is a smaller list than the EFF Diceware list; word counts are not interchangeable.
No password has been generated or saved.
Generation runs in your browser after the page loads. The result is not sent to Passary or saved by this tool. Copying puts it on your device’s clipboard; clearing the result does not clear that clipboard.
Random words, rather than a familiar quote
A sentence you choose yourself can be predictable even when it looks long. This tool selects each word independently using your browser’s cryptographic random source. Eight words from its 864-word list provide about 78 bits of randomness under that model; separators do not add randomness when their choice is fixed.
How local generation works
The generator uses your browser’s Web Crypto random source with rejection sampling to avoid modulo bias. It does not use a remote password service, put results in a URL, or keep a result history. You can generate again without a connection once the page and its scripts have loaded; opening or reloading this public page offline is not guaranteed.
A local generator still depends on a trustworthy browser and device. Copy only when you need the result, and remember that clipboard history, other software, or someone looking at your screen may expose it.
Choose a word count for the actual list
Different word lists give different amounts of randomness per word. This is Passary’s 864-word list, not EFF’s 7,776-word long list. Do not treat six words from every generator as equally strong. Increasing the word count increases the number of possibilities, but it does not protect a compromised device or solve missing recovery copies.
Keep access after you save it
If this is a vault master password, prepare your recovery materials while you still have access. A vault backup is useful only with its matching credentials and any required keyfile. Avoid keeping the only copy of a master password inside the vault it unlocks.
- Generate a random character password
- Choose a master passphrase and plan recovery
- Back up your password vault and test a restore
- Compare free password managers and their limitations
