How it works
What actually makes a password strong?
Length matters more than complexity rules. A longer password drawn from a smaller character set is usually stronger than a short one stuffed with symbols — each extra character multiplies the number of guesses an attacker needs, while an extra required symbol only adds a little. Aim for at least 16 characters when the site allows it.
Are the passwords this tool generates stored anywhere?
No. Every password is generated using the Web Crypto API (crypto.getRandomValues) directly in your browser — never Math.random(), which is not cryptographically secure. Nothing is sent to a server, logged, or saved anywhere.
How often should I rotate passwords?
Only when there is a reason to — a breach, shared access ending, or a site that was compromised. Routine forced rotation on a healthy account tends to push people toward weaker, more predictable passwords, so a long random password left alone is usually better than a mediocre one changed every 90 days.
Is it safe to use this for a real account password?
Yes. Generation happens entirely client-side using a cryptographically secure random source, so the password never exists anywhere but your browser until you paste it in. Use a password manager to store it rather than relying on memory.
