What is Password Generator?
Password Generator is a powerful tool that creates cryptographically secure random passwords based on your specifications. It uses the Web Crypto API's crypto.getRandomValues() method to ensure true randomness and security.
You can customize password length (4-128 characters), choose which character types to include (uppercase, lowercase, numbers, symbols), and apply advanced filters to exclude similar or ambiguous characters.
Why Use Password Generator?
Strong, unique passwords are essential for protecting your online accounts. Using a secure password generator ensures your passwords are truly random and difficult to crack.
Client-side generation ensures your passwords never leave your device - everything is processed locally in your browser for maximum security and privacy.
The tool helps you create passwords that meet common security requirements while avoiding problematic characters that can be easily confused.
Common Use Cases
Account Registration: Generate strong passwords when creating new online accounts for maximum security.
Password Updates: Create new passwords when updating credentials for existing accounts or following a security breach.
API Keys & Secrets: Generate secure random strings for API authentication, webhooks, or application secrets.
Development & Testing: Create test passwords for development environments that meet security requirements.
Bulk Generation: Generate multiple passwords at once for setting up multiple accounts or users.
How to Use Password Generator
1. Set Password Length: Use the slider to choose your desired password length. We recommend at least 16 characters for strong security.
2. Select Character Types: Check the boxes for the character types you want to include - uppercase letters, lowercase letters, numbers, and symbols.
3. Configure Advanced Options: Optionally exclude similar characters (like i, l, 1, O, 0) or ambiguous symbols to avoid confusion.
4. Set Batch Size: If you need multiple passwords, specify how many to generate (1-50).
5. Generate: Click the Generate button to create your passwords using cryptographically secure randomness.
6. Copy & Use: Copy individual passwords or use Copy All to get all generated passwords at once.
Password Security Best Practices
Length Matters: Longer passwords are exponentially harder to crack. Aim for at least 16 characters.
Use All Character Types: Including uppercase, lowercase, numbers, and symbols increases password complexity.
Unique Passwords: Never reuse passwords across different accounts. Each account should have its own unique password.
Password Manager: Store your generated passwords in a reputable password manager for safe keeping.
Regular Updates: Change passwords regularly for sensitive accounts, especially after security incidents.
Two-Factor Authentication: Combine strong passwords with two-factor authentication for enhanced security.
Security & Privacy
All password generation happens entirely in your browser using the Web Crypto API. No passwords are ever sent to our servers or stored anywhere.
We use crypto.getRandomValues() which provides cryptographically secure random numbers, ensuring your passwords are truly unpredictable.
The tool is completely client-side, meaning your generated passwords exist only in your browser's memory until you copy them or refresh the page.
