Password Generator
Create strong, secure passwords instantly — all processing happens in your browser
Cryptographically Secure
Uses the Web Crypto API to generate truly random passwords. No predictable patterns.
Privacy First
All password generation happens in your browser. Nothing is ever sent to a server.
Instant & Free
Generate unlimited passwords instantly with no sign-up required. 100% free forever.
How to Use the Free Password Generator
- 1Set Your Password Preferences: Use the slider to choose your desired password length from 8 to 128 characters. Select which character types to include: uppercase letters, lowercase letters, numbers, and special symbols. You can also exclude ambiguous characters like l, 1, I, O, and 0 for easier reading.
- 2Generate Secure Passwords: Click the "Generate Passwords" button to create up to 10 unique passwords at once. Each password is generated using the Web Crypto API for cryptographic randomness. The strength meter and entropy calculator show you exactly how secure each password is.
- 3Copy and Store Your Password: Click the "Copy" button next to your preferred password to copy it to your clipboard. Store it in a trusted password manager for safekeeping. Never reuse passwords across multiple accounts.
Key Features
- -Cryptographically Secure Randomness: Uses the browser's Web Crypto API (crypto.getRandomValues) instead of Math.random(), ensuring every password is truly random and unpredictable. This is the same level of randomness used by security professionals.
- -Customizable Length and Complexity: Generate passwords from 8 to 128 characters with full control over character types. Mix uppercase, lowercase, numbers, and symbols to meet any website's password requirements.
- -Entropy and Strength Meter: Every generated password displays its entropy in bits, the character pool size, and the total number of possible combinations. The visual strength meter rates passwords from Weak to Very Strong so you can make informed security decisions.
- -Complete Privacy: All password generation happens entirely in your browser. No passwords are ever transmitted to or stored on any server. Your generated passwords exist only on your device until you copy and save them.
- -Batch Generation: Generate up to 10 passwords simultaneously, making it easy to create unique passwords for multiple accounts at once. Pick the one that is easiest to type or remember while still meeting security requirements.
Frequently Asked Questions
What makes a password strong and secure?
A strong password is at least 16 characters long and combines uppercase letters, lowercase letters, numbers, and special symbols. The strength of a password is measured in entropy (randomness in bits). A password with 80 or more bits of entropy is considered very strong. Our generator creates passwords with high entropy using cryptographically secure random number generation, making them resistant to brute-force and dictionary attacks.
Are the generated passwords truly random and secure?
Yes. Our free password generator uses the Web Crypto API (crypto.getRandomValues), which provides cryptographically secure random numbers generated by your browser. This is the same standard used by banks and security applications. Unlike Math.random(), which can produce predictable patterns, the Web Crypto API ensures each character is selected from a truly random distribution. No passwords are ever sent to a server.
Should I exclude ambiguous characters from my password?
Excluding ambiguous characters like lowercase L, uppercase I, the number 1, uppercase O, and the number 0 makes passwords easier to read and type manually. This is useful when you need to write down or dictate a password. However, it slightly reduces the character pool and overall entropy. For maximum security, include all characters. For better readability when typing manually, use the exclude option.
