About Password Generator
This free password generator creates cryptographically secure random passwords directly in your browser. It uses the Web Crypto API (crypto.getRandomValues) to ensure true randomness, making the generated passwords suitable for protecting bank accounts, email, social media, and any other sensitive service.
Weak and reused passwords are the leading cause of account breaches. According to security research, over 80% of data breaches involve compromised credentials. Using a unique, randomly generated password for each account is one of the most effective steps you can take to protect your online identity. This tool makes that easy by generating strong passwords in seconds.
The built-in strength meter evaluates your password based on length and character variety, rating it from Weak to Very Strong. For maximum security, use passwords of at least 16 characters with all character types enabled. All generation happens client-side — your passwords are never transmitted over the internet or stored on any server.
Frequently Asked Questions
How long should a strong password be?
Security experts recommend a minimum of 12-16 characters for strong passwords. Longer passwords are exponentially harder to crack. A 16-character password with mixed character types would take billions of years to brute-force with current technology.
Are the generated passwords truly random?
Yes. This tool uses the Web Crypto API (crypto.getRandomValues), which is a cryptographically secure random number generator built into your browser. This produces genuinely unpredictable passwords suitable for security-critical applications.
Are my generated passwords stored anywhere?
No. Passwords are generated entirely in your browser using client-side JavaScript. Nothing is sent to any server, logged, or stored. Once you close the page, the generated passwords exist only where you saved them.
Why should I exclude ambiguous characters?
Characters like l (lowercase L), 1 (one), I (uppercase i), O (uppercase o), and 0 (zero) look very similar in many fonts. Excluding them prevents confusion when you need to manually type a password, such as entering a Wi-Fi password on a device.
What makes a password strong?
A strong password is long (12+ characters), uses a mix of uppercase letters, lowercase letters, numbers, and symbols, and is randomly generated rather than based on dictionary words or personal information. Avoid reusing passwords across different accounts.
