Passphrase Generator — Free & Secure

Passphrases like "correct-horse-battery-staple" are longer than passwords but far easier to memorize. They leverage the diceware concept — random words strung together with separators — creating credentials you can actually remember without sacrificing security. NIST recommends passphrases for passwords you type manually. A 4-word passphrase has more entropy than most 12-character random passwords. PassCraft generates passphrases using the Web Crypto API for true randomness. Perfect for passwords you need to type frequently but can't use a password manager for.

Frequently Asked Questions

How many characters should my password be?

Security experts recommend 8 characters as the minimum, with 12 characters or more for important accounts. PassCraft lets you generate passwords from 8 to 12 characters (or any length you choose) in seconds.

Is an online password generator safe to use?

PassCraft is safe because it runs entirely in your browser using the Web Crypto API. Unlike other tools, your passwords are generated locally and never transmitted, stored, or logged on any server.

What's the difference between an 8-character and 12-character password?

A 12-character random password is approximately 500,000 times stronger than an 8-character one due to the exponential increase in possible combinations. For most accounts today, 12 characters is the recommended minimum.

Frequently Asked Questions

Is a passphrase more secure than a password?

A 4-word passphrase has more entropy than most 12-character random passwords, while being significantly easier to memorize. NIST recommends passphrases for human- remembered credentials.

How many words should a passphrase have?

Minimum 4 words for security. 5–6 words is recommended for high-security accounts. Each additional word exponentially increases entropy.

Are passphrases safe for all accounts?

Passphrases are ideal for accounts you type manually. For accounts managed by a password manager, a random character password may be equally convenient.
