What is a Password Generator?
A password generator is a tool that automatically creates strong, random passwords using a combination of uppercase letters, lowercase letters, numbers, and special characters. Unlike human-created passwords, generated passwords are truly random and virtually impossible to guess through brute-force attacks. Our free online password generator uses the Web Crypto API for cryptographically secure randomness, ensuring each password is unique and unpredictable.
When to Use a Password Generator
- Creating unique passwords for each online account to prevent credential stuffing attacks
- Generating API keys and secret tokens for development projects
- Setting up strong Wi-Fi passwords for your home or office network
- Creating master passwords for password managers
- Generating temporary passwords for new team members or clients
Frequently Asked Questions
How long should my password be?
Security experts recommend at least 12-16 characters for standard accounts and 20+ characters for sensitive accounts like banking or email. Each additional character exponentially increases the time needed to crack the password.
Are generated passwords safe to use?
Yes. Our password generator runs entirely in your browser using the Web Crypto API. No passwords are sent to any server, stored, or logged. The generation happens 100% client-side on your device.
Should I include special characters in my password?
Yes. Including uppercase, lowercase, numbers, and symbols maximizes the character pool, making brute-force attacks exponentially harder. A 16-character password with all character types would take billions of years to crack.
How often should I change my passwords?
Modern security guidance (NIST) no longer recommends regular password rotation unless there's evidence of a breach. Instead, focus on using unique, strong passwords for each account and enable two-factor authentication.
What makes a password strong?
A strong password is long (16+ characters), uses all character types, is completely random (not based on words or patterns), and is unique to each account. Our generator satisfies all these criteria automatically.
