Free Passphrase Generator
Create strong, memorable passphrases made of random words. Everything happens in your browser — nothing is stored, logged, or sent anywhere.
What Is a Passphrase Generator?
A passphrase generator creates a password made of several random, unrelated words strung together, instead of a single string of random characters. A passphrase like Coral-Trumpet-Window-42 can be just as hard to crack as a shorter random password, while being noticeably easier for a human to remember and type.
This free passphrase generator picks each word using your browser’s cryptographically secure random number generator, the same technology used by password managers, so the result is genuinely unpredictable rather than following a pattern.
How to Use This Passphrase Generator
- Choose your word count. 5 to 6 words is a solid baseline for most accounts; use more for anything highly sensitive.
- Pick a separator. Dashes and dots are easy to read; a space works well if the site allows it.
- Toggle capitalization and numbers to meet sites that require mixed case or digits.
- Generate and copy. Every change regenerates automatically. Click Copy to save it to your clipboard.
- Store it in a password manager, or memorize it if it’s your master password.
Passphrase vs. Random Password: Which Should You Use?
Both a passphrase and a fully random password can reach the same level of security — they just get there differently. A random password packs unpredictability into fewer characters, since every single character is drawn from a large pool of letters, numbers, and symbols. A passphrase needs more total characters to reach the same strength, because it’s built from whole words rather than individual characters, but it’s often much easier to type and recall without a password manager.
A common approach: use this passphrase generator for passwords you need to type or remember yourself, like a password manager’s master password, and use a random password generator for everything else that gets saved and auto-filled.
Frequently Asked Questions
What is a passphrase generator?
A passphrase generator creates a password made of several random, unrelated words strung together, such as correct-horse-battery-staple, instead of a single string of random characters. Passphrases can be easier to remember while still being very hard to guess, as long as enough words are used.
How many words should a passphrase have?
Most security guidance recommends at least 5 to 6 random words for a passphrase used on an important account. Each additional word significantly increases the number of possible combinations, making the passphrase harder to guess or crack.
Is a passphrase safer than a random password?
Both can be equally safe if long enough. A random password reaches strong security in fewer total characters because every character is drawn from a large pool, while a passphrase needs more words to reach the same level of unpredictability. Passphrases are often chosen because they are easier for a person to remember and type.
Can I use a passphrase for my password manager?
Yes. A long, random passphrase is a common and recommended choice for a password manager’s master password, since it is the one password you actually need to memorize and type yourself, rather than copy and paste.
Does this passphrase generator store what I create?
No. This passphrase generator runs entirely in your browser using your device’s cryptographically secure random number generator. Nothing is sent to a server, logged, or stored. Closing or refreshing the tab clears it completely.
