Generate secure yet memorable passphrases using random words. Enhance your security with easy-to-type credentials.
Diceware-style phrase generation with casing/separator controls and memorability scoring
Passphrases are both more memorable and more secure than random character strings. The Passphrase Generator combines random dictionary words into long, high-entropy phrases — easier to type, harder to crack, and compliant with modern NIST password guidance.
NIST 800-63B recommends prioritizing length over complexity. Long passphrases with simple words outperform short passwords with forced substitutions (like P@ssw0rd) in both security and usability.
Need character-based passwords instead? Use the Strong Password Generator for symbol-heavy options.
A 5-word passphrase from a large wordlist (7776+ words) exceeds 64 bits of entropy and is significantly harder to brute-force than typical 8-character passwords.
NIST 800-63B emphasizes length over complexity. Passphrases are both longer and more memorable than complex short passwords.
It adds entropy, but the primary strength comes from multiple random words. A 6-word passphrase without symbols beats a 4-word one with symbols.
