Password Generator

Passwords use crypto.getRandomValues for true cryptographic randomness. A 16-character password with mixed character types has over 10^28 possible combinations.

Length is the most important factor. Use at least 16 characters with a mix of uppercase, lowercase, numbers, and symbols. Avoid dictionary words and personal information.

Passwords use crypto.getRandomValues for true cryptographic randomness. Characters are independently selected from your chosen character sets, and the result is Fisher-Yates shuffled to ensure the password contains at least one character from each selected set.

Yes. Password managers generate, store, and auto-fill strong unique passwords for every site. This tool is useful for quick generation, service account credentials, API keys, and situations where a password manager isn't available or practical.

The formula is characters^length. A 16-character password with all 4 character sets (72 possible characters) has 72^16 ≈ 5.2 × 10^29 possible combinations. At 1 billion guesses per second, it would take about 16 trillion years to try them all.

No. Passwords are generated entirely in your browser's memory and are not stored, logged, or transmitted anywhere. The page can work fully offline. Once you navigate away, the generated password exists only if you saved it.

Never. All generation happens entirely in your browser. No passwords are stored, logged, or sent anywhere. You can verify this by disconnecting your internet.
