Secure Passphrase Generator
A secure passphrase generator creates maximum-entropy passphrases suitable for the most sensitive credentials — 6 words, a random number, and a symbol, achieving over 75 bits of entropy while remaining memorable. Ideal for password manager master passwords and high-security accounts.
Why 6-word passphrases for high-security accounts
A 6-word passphrase from a 2,000-word list achieves ~66 bits of entropy — equivalent to a 10-character fully random password. Adding a 2-digit number (+7 bits) and a symbol (+3 bits) pushes this above 75 bits, which exceeds NIST recommendations for all account types including privileged access. This makes it suitable as a KeePass master password, Bitwarden master password, or encryption passphrase.
Secure passphrases vs. complex passwords
For credentials you must remember and type, a 6-word secure passphrase is often preferable to a 12-character random password. The passphrase achieves similar entropy while being far more typable and memorizable. For machine-stored credentials where you'll paste, a 16-character random password is equally valid.
Frequently Asked Questions
A 6-word passphrase from our 2,000-word list has ~66 bits of entropy. Adding a number and symbol brings it above 75 bits — considered strong for all use cases including privileged account access.
Yes — a 6-7 word passphrase is the ideal master password. It provides strong security (75+ bits of entropy) while being genuinely memorizable. Practice typing it daily for the first week to build reliable recall.
Excellent choice. KeePass recommends a long, memorable master password — a 6-word passphrase with number and symbol provides the recommended strength (75+ bits) while being typable.
Yes — for full-disk encryption (VeraCrypt, LUKS), a 6-7 word passphrase with number and symbol is appropriate. The entropy exceeds most encryption strength requirements, and you'll rarely need to type it, making occasional typing feasible.
