Is this password generator safe to use?

Yes. This tool uses the Web Crypto API (crypto.getRandomValues) which runs entirely in your browser. Your generated passwords are never sent to any server — we physically cannot see them.

What does entropy mean for passwords?

Entropy measures how unpredictable a password is, in bits. A password with 60+ bits of entropy is considered strong. 80+ bits is very strong and essentially uncrackable by brute force with current technology.

Password strength guide

Weak — Under 8 chars, one character type. Crackable in seconds.

Fair — 8–11 chars, mixed types. Better, but not for important accounts.

Good — 12–15 chars, 3+ types. Suitable for most accounts.

Very Strong — 16+ chars, all types. Use for banking, email, and password managers.

Frequently asked questions

How long should my password be? +

At least 12 characters for standard accounts, and 16+ for sensitive ones like banking or email. Longer is exponentially harder to crack — a 20-character password is millions of times stronger than a 12-character one.

Is this generator safe — can you see my passwords? +

No. This tool uses the Web Crypto API and runs entirely in your browser. Your generated passwords are never transmitted to any server. We physically cannot see them.

What does entropy mean? +

Entropy measures how unpredictable a password is, in bits. A password with 60+ bits is considered strong. Above 80 bits is essentially uncrackable by brute force with current computing technology.

Should I use a password manager? +

Yes — absolutely. A password manager (like Bitwarden, 1Password, or the one built into your browser) lets you use a unique, strong password for every site without having to memorise them. Generate your passwords here, then save them in your manager.
