Passphrase Generator
Generate a random multi-word passphrase in one click. The generator runs locally in your browser; use a unique result and store it safely.
About this tool
Generates random passphrases from a large wordlist using cryptographically secure randomness. Choose word count (3-8), separator style, capitalisation and optional number/symbol additions.
Anyone who needs a strong, memorable password — especially for master passwords, computer logins, email accounts and any account you need to type rather than autofill. Used in the UK, US, Australia, Canada, Singapore, UAE and worldwide.
All passphrase generation happens in your browser using window.crypto.getRandomValues — the same cryptographic standard used in security software. No passphrase is ever transmitted to any server or stored anywhere.
How it works, limits and privacy
The default is five independent words from the EFF 7,776-word list. Selection uses crypto.getRandomValues with rejection sampling. The displayed bits describe the generator’s search space—not measured entropy of a user-edited phrase and not a guarantee of account security.
