Passphrase Generator
Passphrases combine several random common words into one long, easy-to-remember string — often stronger than a short complex password and far easier to type or recall. Everything is generated locally in your browser; nothing is transmitted.
How to Use the Passphrase Generator
- Choose how many words to include — more words means a longer, stronger passphrase.
- Pick a separator to place between words, or none at all.
- Optionally capitalize each word and/or append a random number for extra variety.
- Click "Generate Passphrase" and copy the result with one click.
Why Use This Tool?
Is a passphrase actually more secure than a password?
Often, yes. Security depends on total entropy — the number of possible combinations an attacker would need to try. A 5-word passphrase drawn from a list of ~180 common words has roughly the same or greater entropy as a much shorter random password, while being dramatically easier for a human to remember and type correctly.
Where does the word list come from, and is anything sent to a server?
The word list is a fixed set of common, simple English words built directly into this page's code. Word selection uses your browser's cryptographically secure random number generator (crypto.getRandomValues). No word, passphrase, or setting you choose is ever transmitted anywhere — the entire process runs offline in your browser.
Should I add numbers and separators?
Yes, when the site or system allows it. Adding a random number and a non-space separator increases the character variety, which can help satisfy password policies that require digits or symbols alongside your memorable word combination.
How many words should I use?
For most personal accounts, 4–5 words is a strong, practical balance of security and memorability. For high-value accounts, consider 6 or more words for extra protection.
