What Makes a Password Strong?

Two things: length and randomness. Every added character multiplies the number of possibilities; a random 16-character password with mixed character sets would take modern hardware centuries to brute-force, while an 8-character word-based one can fall in hours. This tool draws characters with crypto.getRandomValues — the browser's cryptographically secure generator — so the result contains no guessable pattern.

The password is generated on your device and never sent anywhere. For daily use, store passwords in a password manager and use a unique one per site.

Frequently Asked Questions

How long should my password be?

At least 12 characters for regular accounts and 16+ for critical ones (email, banking). Length beats complexity: a 16-character lowercase password is stronger than an 8-character one with symbols.

Is the generated password sent to a server?

No. It is produced by your browser's crypto.getRandomValues API entirely on your device and never leaves it. Refreshing the page destroys it.

Should I use the same password on multiple sites?

Never. A breach at one site would expose all your accounts. Generate a unique password per site and keep them in a password manager.
