About This Calculator
The "correct horse battery staple" idea: a string of four random common words is far more memorable than random characters while offering similar entropy.
This generator picks words from a fixed list and combines them with your chosen separator, optionally adding two digits and a symbol for extra strength.
Generation runs locally in your browser.

Frequently Asked Questions
How secure is a passphrase?
Four words from a 50-word list give roughly 4 × 5.6 ≈ 22 bits of entropy from the words alone. The added digits/symbol and separator choice raise that further. For high-security needs use 6+ words.
Are these as strong as random character passwords?
For practical purposes yes, because passphrases are longer and far easier to remember, so users are less tempted to reuse or write them down.
