Passphrase Generator
Generate long, memorable passphrases built from random words for safer logins.
Create strong but memorable passphrases
Instead of short, hard-to-remember passwords, use a string of random words. This gives you both high security and something you can actually recall.
Tip: treat these like any other secret—store them in a password manager and never reuse the same passphrase across different sites.
Passphrase settings
Adjust how many words and passphrases you want.
4–6 words is a good practical default.
Generate up to 50 passphrases in one batch.
Generated passphrases
Copy individual passphrases or the full list. Store them securely—there is no recovery if you lose them.
Click "Generate passphrases" to create a list. They will appear here as a scrollable list, one per line.
Why use passphrases?
Passphrases string together multiple random words instead of short, complex-looking passwords. That makes them much harder to crack but still easier for humans to remember.
Use this generator to create long, random passphrases and store them in a password manager. Avoid including personal details or predictable patterns like movie quotes or song lyrics.
Secure & Memorable
Forget "Tr0ub4dor&3". Use random word combinations that are easy for humans to remember but mathematically impossible for computers to guess.
Human Friendly
Uses real English words, making your password easy to recall without writing it down.
High Entropy
4 random words have more entropy (~52 bits) than an 8-character complex password.
Typing Flow
Great for mobile devices or master passwords where typing special chars is annoying.
Brute Proof
Extremely resistant to dictionary attacks when using 4 or more random words.
How this Passphrase Generator works
This security tool generates strong, memorable passphrases consisting of random words strung together, offering high entropy with better memorability than complex random strings. Based on the Diceware concept, it selects words from a curated list of thousands of English words. Users can customize passphrase length, choose separators (hyphen, space, period), and optionally capitalize words or add numbers for specific requirements. The entropy strength is calculated and displayed instantly. Applications include creating master passwords for password managers, generating secure login credentials for critical accounts, and replacing hard-to-remember random strings with sentences that are mathematically difficult to guess but easy to type. All generation happens locally in the browser for maximum security.
How to Use

Example Usage
A typical setup: 4–6 random words, separated by hyphens, with a small random number at the end.
