Need a password you can actually remember without sacrificing security? A passphrase generator creates random word combinations like correct-horse-battery-staple — high entropy, low frustration. Use our free Password Generator in Passphrase mode to create one instantly in your browser.
Why Passphrases Can Beat Random Character Passwords
Security is about total entropy, not just how random individual characters look. A 16-character password mixing letters, numbers, and symbols is strong — but a 4-word passphrase drawn from a 1,000-word list has roughly 40 bits of entropy per word, or about 160 bits total. That is comparable to or better than many random passwords people actually use in practice.
The famous XKCD #936 comic illustrated this perfectly: four common words chosen at random are easier to memorize and type than a mangled string like Tr0ub4dor&3, yet harder for attackers to guess because the search space is enormous.
Passphrase vs Random Password — When to Use Each
- Use a passphrase for master passwords, WiFi passwords you type often, and accounts where memorization matters.
- Use a random password for website logins stored in a password manager, API keys, and one-time credentials you will copy-paste.
- Use 5–6 words for email, banking, and password manager vaults; 4 words is fine for most everyday accounts.
How Word Count Affects Security
Each additional random word multiplies the number of possible combinations. Moving from 3 to 4 words does not add a little security — it multiplies the attack space by roughly 1,000 (with a 1,000-word list). That is why 4+ words is the standard recommendation for passphrases today.

Frequently Asked Questions
Are passphrases more secure than random passwords?
A 4-word passphrase from a large wordlist has very high entropy and is considerably harder to crack than many short random passwords — and far easier to remember and type.
How many words should a passphrase have?
4 words provides strong security for most purposes; 5-6 words is excellent for high-value accounts like email or password manager master passwords.
Can I use a passphrase as my password manager master password?
Yes — a long, memorable passphrase is one of the best choices for a master password since it's both high-entropy and easy to remember without writing it down.
What separates a good passphrase from a bad one?
True randomness in word selection matters most — a phrase you made up yourself is far less random than words chosen by a generator, since humans tend toward predictable patterns.
