Write this on paper and store it physically
Your master passphrase is the one password you should write down. Keep it somewhere secure — a locked drawer, a safe, or with important documents. If you lose access to your password manager, this paper copy is your recovery plan. Never store it digitally (no notes apps, no cloud docs, no photos).
🔒Your privacy is built in. All passphrases are generated locally in your browser using a built-in word list. Nothing is sent over the internet, logged, stored, or transmitted — not even temporarily. The page works completely offline after the first load.
⚠️
Important: master password only
This tool is for generating your password manager master passphrase only — the one password you need to remember. All other passwords should be random strings generated and saved by your password manager automatically. Using passphrases for every site defeats the purpose of having a password manager.
