What is Password Generator?
A password generator creates random, secure passwords that are difficult for attackers to guess or crack. This tool uses your browser's built-in Web Crypto API (crypto.getRandomValues) for cryptographically secure random number generation, ensuring passwords are truly unpredictable. You can customize length and character types to meet any website's requirements.
Strong passwords are essential for protecting your accounts from brute-force attacks, dictionary attacks, and credential stuffing. Security experts recommend unique, random passwords of at least 12 characters for important accounts.

Common Questions
How secure are the generated passwords?
Extremely secure. We use the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers. This is the same standard used by browsers for HTTPS encryption. Combined with sufficient length and character variety, these passwords are practically impossible to crack through brute force.
What makes a password strong?
Password strength depends on length and complexity. A 16-character password with uppercase, lowercase, numbers, and symbols would take billions of years to crack. For maximum security: use 16+ characters, include all character types, never reuse passwords, and consider using a password manager to store them.
Are my passwords saved anywhere?
No. Passwords are generated entirely in your browser using JavaScript. We have no server-side processing, no database, and no way to see or store your passwords. When you leave the page, the password exists only in your clipboard (if copied) or is gone completely.
Should I include symbols in my password?
Yes, when possible. Symbols significantly increase the character pool from 62 (letters + numbers) to 90+, making passwords exponentially harder to crack. However, some websites restrict which symbols are allowed. If a site rejects your password, try generating one without symbols.
How long should my password be?
At minimum 12 characters, but 16+ is recommended for important accounts. Each additional character exponentially increases security. A 16-character password with all character types has approximately 10^30 possible combinations - far beyond what any computer can crack in a human lifetime.
