About Password Generator
The Password Generator creates cryptographically secure random passwords with configurable length and character sets. Choose any combination of uppercase letters, lowercase letters, numbers, and symbols. Set a minimum length and exclude ambiguous characters (0, O, l, 1, I) for easier reading.
All randomness comes from the browser's Web Crypto API (crypto.getRandomValues), which is cryptographically strong — not the weak Math.random() function.
Strong passwords are your first line of defense against account compromise. A 16-character password using all character sets has more than 10^29 possible combinations, making it effectively unbreakable by brute force.
Your generated passwords are never stored, logged, or transmitted. Everything happens locally in your browser.
How to Use Password Generator
Set your desired password length (8–128 characters).
Toggle character sets: uppercase (A-Z), lowercase (a-z), numbers (0-9), symbols (!@#$...).
Optionally exclude ambiguous characters like 0, O, l, 1, and I.
Click Generate. Copy the password immediately.

Frequently Asked Questions
Is the password generated securely?
Yes — the Web Crypto API (crypto.getRandomValues) is used for all randomness, not Math.random(). This provides cryptographically strong randomness.
How long should my password be?
At least 16 characters for important accounts. NIST recommends length over complexity — a 20-character password is far stronger than an 8-character one with special characters.
Should I use a password manager?
Yes — a password manager lets you use a unique, long, random password for every account without needing to remember them. Use a generator like this one together with a password manager.
Are generated passwords saved anywhere?
No — passwords are generated entirely in your browser and are never stored, logged, or transmitted anywhere.
What makes a password strong?
Length is the most important factor. Using all character sets (uppercase, lowercase, numbers, symbols) increases the character space, but length has a much larger impact on entropy.
Can I generate multiple passwords at once?
Yes — set the count to generate multiple passwords in a single click for batch use cases.
