How to Use Password Generator
- Choose your desired password length using the slider (16+ characters recommended).
- Select character sets to include: uppercase, lowercase, numbers, and symbols.
- Check 'Avoid Ambiguous Characters' to prevent confusing letters like 1, l, I, 0, and O.

About this Tool
All passwords are created directly on your device using the browser's crypto.getRandomValues API (CSPRNG). Passwords never touch any network connection or remote server.
Frequently Asked Questions
Common questions about Password Generator, accuracy, and browser-side security.
Passwords use the browser's cryptographic pseudo-random number generator (CSPRNG), ensuring maximum unpredictability and high entropy.
Never. All calculations happen entirely in your web browser. No network requests are made, and nothing is saved or transmitted.
Length is the most critical factor. A 16+ character password combining uppercase, lowercase, digits, and special characters provides trillions of possible combinations.
Entropy is measured in bits and quantifies how hard a password is to guess through brute-force attacks. 60+ bits of entropy is considered strong for personal accounts.
