Password Strength
What Is a Password Generator?
A password generator is a security tool that creates strong, random passwords with customizable character sets and lengths. Our online password generator helps you create cryptographically secure passwords that are resistant to brute force attacks, dictionary attacks, and other common password cracking methods.
This tool uses advanced algorithms to generate truly random passwords using combinations of uppercase letters, lowercase letters, numbers, and symbols. You can customize the length, character types, and exclude similar or ambiguous characters to meet specific security requirements.
Whether you need passwords for personal accounts, business systems, or security testing, our generator provides reliable and secure password creation with real-time strength analysis.
How Do You Use the Password Generator?
- Set Length: Choose your desired password length (4-128 characters).
- Choose Quantity: Specify how many passwords you want to generate (1-20).
- Select Character Types: Check which character types to include (uppercase, lowercase, numbers, symbols).
- Advanced Options: Optionally exclude similar or ambiguous characters for better readability.
- Generate: Click "Generate Password" to create your secure passwords.
- Copy Results: Use the "Copy to Clipboard" button to save your passwords.
The generator will instantly create random passwords and display their strength analysis, including entropy calculations and estimated crack times.

Frequently Asked Questions
How random are the generated passwords?
Our passwords use cryptographically secure random generation, making them extremely difficult to crack. A 16-character password with all character types has over 95 bits of entropy.
What's the recommended password length?
We recommend at least 12 characters for general use, 16+ for sensitive accounts. Longer passwords are exponentially more secure.
Should I exclude similar characters?
Enable this option if you need to type passwords manually, as it removes characters like 0/O and l/I that can be easily confused.
Is this tool safe to use?
Yes, all password generation happens locally in your browser. No passwords are transmitted or stored on our servers.
