Password Generator
Generate cryptographically secure passwords, passphrases, and PINs. Runs entirely in your browser — nothing is ever sent to a server.
Free Strong Password Generator
81% of data breaches are caused by weak or reused passwords. Our password generator uses the browser's built-in Web Crypto API to generate truly random, cryptographically secure passwords — not pseudo-random strings like most online tools.
Choose from three generation modes: Random Password (maximum entropy, perfect for any account), Passphrase (multiple random words joined by a separator — easy to type and still highly secure), or PIN (for numeric input fields).
Customize length up to 128 characters, toggle character sets, exclude ambiguous characters like 0/O/l/1, enforce minimum numbers and symbols, and view real-time strength scoring with estimated crack time. Every password vanishes when you close the tab — zero storage, zero tracking.
Password Generator Features
- Cryptographic Randomness — Uses the Web Crypto API for true random number generation, ensuring passwords cannot be predicted.
- Three Generation Modes — Random passwords for maximum security, passphrases for memorability, and PINs for numeric-only fields.
- Customizable Length — Generate passwords from 8 to 128 characters to meet any security requirement.
- Character Set Control — Toggle uppercase, lowercase, numbers, and symbols independently. Set minimum counts for numbers and symbols.
- Exclude Ambiguous Characters — Remove confusing characters like 0/O, l/1, and I to avoid mistakes when typing passwords manually.
- Strength Meter — Real-time entropy calculation and estimated crack time give you confidence in your password's security.
- Generation History — View your last 10 generated passwords within the session for easy comparison and selection.
How to Create a Strong Password
A strong password should be at least 12 characters long and include a mix of uppercase letters, lowercase letters, numbers, and symbols. The longer and more varied the character set, the exponentially harder it is to crack.
For maximum security, use a unique password for every account. Password managers make this practical by storing and auto-filling your passwords. Generate a strong, unique password here and save it in your password manager.
If you need a password you can actually remember, use the Passphrase mode. A four-word passphrase like "Coral-Bliss-Nexus-Eagle" is both easy to type and extremely difficult to brute-force, with entropy comparable to a 12-character random password.
Frequently Asked Questions
Are the generated passwords truly random?
Yes. The password generator uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers — far superior to Math.random() used by most online tools.
Are my passwords stored anywhere?
No. Passwords are generated entirely in your browser and are never transmitted to any server. When you close the tab, the passwords are gone forever.
How long should my password be?
Security experts recommend at least 12 characters for standard accounts and 16+ characters for sensitive accounts like banking or email. Our default is 16 characters with all character types enabled.
What is a passphrase?
A passphrase is a password made up of multiple random words joined by a separator (like dash or space). Passphrases are easier to remember than random character passwords while still being highly secure.
