Password Generator.
Generate strong, secure passwords instantly. Fully client-side — your passwords never leave your browser.
Password requirements
Why use our Password Generator?
Security starts with a strong, unique password. Our generator uses cryptographically secure randomness (Web Crypto API) to create passwords that are truly unpredictable, protecting your accounts from hackers and brute-force attacks.
Cryptographically Secure: Uses the Web Crypto API — the strict standard trusted by modern browsers and operating systems for high-level security.
100% Private & Local: Your passwords are generated entirely within your own browser. They never leave your device and are never transmitted to our servers.
Fully Customizable: Easily control the exact length (4–128 characters) and select the specific character types (uppercase, numbers, symbols) required by different websites.
How to Generate a Strong Password
Choose your length: using the slider or number input. We recommend at least 16 characters for maximum security.
Select your character types: including uppercase, lowercase, numbers, and special symbols each drastically increases the password's strength.
Click Generate: at any time to instantly create a new password with your current settings.
Click Copy: to save the password to your clipboard, then paste it directly into your new account or password manager.
Frequently Asked Questions
Is this password generator secure?
Yes. We use the Web Crypto API (crypto.getRandomValues) which provides cryptographically strong randomness — the same standard used by operating systems and security software.
Are my passwords stored or transmitted?
Never. All generation happens entirely in your browser using JavaScript. No password is ever sent to our servers.
How long should my password be?
For most accounts, 16 characters with mixed types is excellent. For high-value accounts (banking, email), use 24+ characters and enable all character types.
What does password strength mean?
Strength is measured in bits of entropy: length × log₂(charset size). More bits means more possible combinations and longer crack times. 60+ bits is strong; 128+ bits is practically uncrackable.
Can I use special symbols everywhere?
Most modern websites and apps accept special symbols. However, some older systems have restrictions — if a site rejects your password, try disabling symbols and regenerating.
Should I use a password manager?
Yes, absolutely. Password managers let you use a unique, strong password for every account without memorizing them. Use this generator to create passwords and store them in your manager.
What makes a password weak?
Short length, using only one character type (e.g. all lowercase), predictable patterns, or reusing the same password across sites. Our strength meter shows you exactly where you stand.
