Why Use a Strong Password Generator?
Weak passwords are the leading cause of account breaches. Passivo generates truly random, secure passwords in seconds using the Web Crypto API — no guesswork, no patterns.
Everything runs entirely in your browser. Your passwords are never sent to any server, never logged, and never stored.
What Makes a Password Strong?
Length (16+ characters), randomness (no patterns), and character variety (uppercase, lowercase, numbers, symbols). Our generator enforces all three by default.
Random vs Memorable Passwords
Random passwords offer maximum security. Memorable passphrases like correct-horse-battery-staple are easier to type while still being very strong.
Frequently Asked Questions
Is Passivo really free? +
Yes — 100% free with no sign-up, no ads, and no limits.
Are my passwords stored or transmitted? +
No. All generation happens in your browser. Nothing is ever sent to a server.
How long should my password be? +
At least 16 characters for general accounts, 20+ for email and banking.
What is a memorable password? +
A passphrase of random words joined by a separator. Easier to remember, just as strong when using 4+ words.
Should I exclude ambiguous characters? +
Only if you type passwords manually. For passwords stored in a manager, this is unnecessary.
What is password entropy? +
Entropy measures unpredictability. 80+ bits of entropy is considered very strong.
