Why Strong Passwords Matter
Weak passwords are the #1 cause of data breaches. A strong password should be at least 12 characters long and include a mix of uppercase, lowercase, numbers, and symbols. Our generator uses cryptographically secure random number generation (Web Crypto API) for maximum security.
Password Best Practices
Use a unique password for every account
Never share passwords via email or text
Use a password manager to store them
Enable two-factor authentication (2FA)
Change passwords if a breach is detected
Time to Crack
A 6-character lowercase password can be cracked in seconds. A 12-character mixed password takes centuries. A 16-character password with symbols would take trillions of years to brute force with current technology. Length is the most important factor in password strength.
100% Client-Side
Your passwords are generated entirely in your browser using the Web Crypto API. No passwords are ever transmitted to our servers or stored anywhere. Once you leave this page, the generated passwords exist only where you saved them. Your security is our priority.
Frequently Asked Questions
How does this password generator work?
It uses the Web Crypto API (crypto.getRandomValues()) built into your browser to generate cryptographically secure random numbers. These are mapped to your selected character sets to produce truly random passwords.
What makes a password strong?
Password strength depends on length and character diversity. A 16-character password with uppercase, lowercase, numbers, and symbols has approximately 105 bits of entropy, making it virtually impossible to crack by brute force.
Is it safe to use an online password generator?
Yes, as long as the generator runs entirely in your browser (client-side). Our tool never sends your generated passwords to any server. You can verify this by checking your browser's network tab - no data is transmitted when you generate a password.
How long should my password be?
We recommend at least 16 characters for important accounts (banking, email). For less critical accounts, 12 characters with mixed character types is generally sufficient. For maximum security, use 20+ characters.
