What is Password Generator?
Password Generator creates cryptographically secure random passwords using the Web Crypto API built into your browser. You can customize password length from 8 to 128 characters, toggle character types (uppercase, lowercase, numbers, symbols), exclude ambiguous characters, and generate passwords in bulk. Every password is generated entirely client-side with true cryptographic randomness — nothing is ever sent to a server.
How to Use
- Adjust the length slider and toggle the character types you need (uppercase, lowercase, numbers, symbols)
- Optionally enter characters to exclude, such as ambiguous characters like 0, O, I, l, 1
- Click Generate Password for a single password, or set a count (1-10) and use Bulk Generation
- Click the password to copy it to your clipboard, or use the Copy/Download buttons for bulk results
Use Cases
- Creating strong, unique passwords for new accounts and services
- Generating secure API keys, tokens, or secrets for development environments
- Producing random strings for database seeds, test fixtures, or configuration values
- Batch-generating temporary passwords for user onboarding or team provisioning
Privacy & Security
All password generation happens entirely in your browser using crypto.getRandomValues() from the Web Crypto API, which provides true cryptographic randomness. No passwords are ever transmitted, logged, or stored on any server. Your generated passwords exist only in your browser's memory and clipboard. You can verify this by checking the network tab in your browser's developer tools — you'll see zero outbound requests.
