Passphrase Generator
Secure Diceware Passphrase Generator
Create a memorable passphrase from randomly chosen words. Everything happens on your device—nothing is sent or saved.
Your secure passphrase
Words worth remembering.
77 bits of estimated entropy
Independent words, securely chosen
Each word is selected with your browser's secure random generator from the 7,776-word EFF Diceware list. Your passphrase never leaves this page.
How do I generate a memorable passphrase?
Choose the number of words and a separator, then copy the generated passphrase. Each word is selected independently from the EFF Diceware list using secure randomness.
What makes a passphrase strong?
More independently selected words increase the number of possible combinations. Keep the random words rather than replacing them with a familiar quote or sentence, and use a different passphrase for each account.
Is my passphrase saved or uploaded?
No. The wordlist is downloaded to your browser, and the passphrase is generated locally. This page does not save or upload it.
