Random Passphrase Generator

Create private random passphrases made from multiple words. A secure passphrase is useful when you need a secret that is strong but easier to type than a dense string of symbols.

When to use a passphrase

Use a passphrase for device logins, master passwords, encrypted archives, and other places where you may need to type the secret manually. A passphrase with several random words can be easier to remember while keeping a large search space.

How to make passphrases stronger

Random word password recommendations

For a word-based password, randomness matters more than clever wording. Do not use a familiar phrase with substitutions. Use unrelated random words, keep the passphrase unique, and increase the word count when the account protects email, finance, work, backups, or encryption.

Secure passphrase generator

A secure passphrase generator should choose words randomly, keep the result private, and help you create a unique secret for one account or device. This page creates passphrases locally in the browser for that purpose.

Privacy model

The generator runs locally in your browser. Generated passphrases are not sent to a server, stored in an account, or tracked. For implementation details, read the security model.

Common questions

What is a secure passphrase?

A secure passphrase is made from random words, uses enough length, and is unique to one account or device.

How many words should a random passphrase use?

Use at least four random words for common uses and more words for sensitive accounts, master passwords, or encryption keys.

Is a passphrase better than a password?

A passphrase is often better when you need to type or remember the secret. A random character password is usually better when a password manager stores it.
