Diceware Passphrase Generator
Memorable word-based passphrases, diceware style.
About this tool
A passphrase of random common words is easier to remember and type than symbol soup, and its security is honest arithmetic: each word drawn uniformly from an N-word list adds log₂(N) bits. Six words from this list clears the strength of a 12-character random password.
Words are drawn with your browser's CSPRNG. Add separators, digits, or capitalization to satisfy legacy password rules.
Like everything on encrypt.tools, this runs entirely in your browser — nothing you enter is transmitted or stored.
Frequently asked questions about Passphrase Generator
Are word passphrases secure?+
Yes, when words are chosen randomly. Six random words from this list exceed the strength of a 12-character random password, while being far easier to type and remember.
What is diceware?+
A method of building passphrases by selecting random words from a fixed list — originally with physical dice. This tool uses your browser's secure random generator instead.
How many words do I need?+
Six gives strong security for most accounts; use more for high-value secrets. The tool shows the exact entropy per phrase.
