What Makes a Strong Password?
A strong password combines length, complexity, and randomness. Our generator uses crypto.getRandomValues(), the Web Crypto API's cryptographically secure random number generator, to ensure true randomness that cannot be predicted.
Password Strength Calculation
Password strength is measured in bits of entropy - the more entropy, the harder the password is to crack. We calculate entropy based on:
- Length: Longer passwords have exponentially more possible combinations
- Character set size: Using more character types (uppercase, lowercase, numbers, symbols) increases possibilities
Why Exclude Ambiguous Characters?
Characters like 0 (zero) and O (letter O), or l (lowercase L), 1 (one), and I (uppercase i) can be easily confused when reading or typing passwords. Excluding them makes passwords easier to use without significantly reducing security.
Security Note
All password generation happens entirely in your browser. No passwords are ever sent to our servers. You can verify this by checking your browser's network tab or reviewing the source code.
Features
Our Password Generator creates strong, random passwords using cryptographically secure randomness (crypto.getRandomValues). This ensures your passwords are truly unpredictable and resistant to brute-force attacks.
Customize your passwords with configurable length from 8 to 128 characters, and choose which character types to include: uppercase letters, lowercase letters, numbers, and special symbols. You can also exclude ambiguous characters like 0, O, l, and 1 to avoid confusion when typing.
Generate multiple passwords at once and use the password strength indicator to ensure your passwords meet security requirements. All generation happens locally in your browser - your passwords are never sent to any server.
