What is a Password Generator?
A Password Generator is a tool that creates strong, random, and secure passwords that are difficult to crack or guess. Our password generator creates high-entropy passwords using a combination of uppercase and lowercase letters, numbers, and special characters to ensure maximum security.
In an age where data breaches and cyber attacks are increasingly common, using strong, unique passwords for each of your accounts is crucial. Our password generator helps you create passwords that resist brute force attacks, dictionary attacks, and other common password cracking methods.
This tool offers customization options including password length, character types, batch generation, and options to exclude similar-looking characters. You can also include or exclude specific characters based on your needs or the requirements of the systems where you'll use the passwords.
How to Use the Password Generator
- Set the number of passwords you want to generate (from 1 to 100)
- Adjust the password length using the slider (4-64 characters)
- Select character types to include (uppercase, lowercase, numbers, symbols)
- Optionally enable "Exclude Similar Characters" to avoid confusion
- Include or exclude specific characters if needed
- Click the "Regenerate" button to create new passwords
- Copy results individually or all at once to your clipboard
- Download results as a text file if needed
- Toggle the "Show Passwords" option to hide sensitive information
Understanding Password Strength
Very Weak
Short passwords with limited character types. These can be cracked quickly and should be avoided for all accounts. Typically includes passwords shorter than 8 characters or those using only numbers or letters.
Weak
Passwords that have minimal complexity or are too short. These provide only basic protection and can be vulnerable to brute force attacks. Often includes passwords with 8-10 characters using only one or two character types.
Fair
Passwords with moderate length and some complexity. These offer adequate protection for low-risk accounts. Typically includes passwords with 10-12 characters using a mix of character types, but may lack sufficient randomness.
Good
Passwords with good length and complexity using multiple character types. Suitable for most online accounts including email and social media. Usually contains 12-16 characters with a good mix of uppercase, lowercase, numbers, and possibly symbols.
Strong
Long passwords with high complexity using all character types. These provide maximum security and are recommended for sensitive accounts like banking, password managers, and email. Typically includes 16+ characters with a diverse mix of character types and high entropy.

How Password Generation Works
This tool uses the browser's cryptographically secure random number generator (CSPRNG) to create high-entropy passwords. For each character position, a random number is generated and mapped to a character from the selected character sets (uppercase, lowercase, numbers, symbols).
The strength indicator analyzes various aspects of your password, including length, character diversity, and complexity. This analysis provides a visual indication of how resistant your password would be against common cracking methods like brute force attacks, dictionary attacks, and pattern-based guessing techniques.
Remember that even the strongest password can't protect you if you're tricked into revealing it or if you use it on an insecure website. Always ensure you're on legitimate websites before entering passwords, especially for financial or sensitive accounts.
