Password Generator – Create Strong, Secure & Random Passwords Instantly
A Password Generator is an essential tool for creating strong, random, and secure passwords that help protect your online accounts and sensitive information. In today's digital world, where data breaches and cyberattacks are increasingly common, using weak or reused passwords can put your identity, finances, and privacy at risk.
This tool helps you generate highly secure passwords using a mix of uppercase and lowercase letters, numbers, and special characters, and even gives you control over complexity and character exclusions to fit your specific needs.
What Is a Password?
A password is a combination of characters used to verify your identity and restrict access to systems, accounts, or devices. A strong password helps prevent unauthorized access and ensures that only you can access your personal or professional data.
What Is Password Strength?
Password strength refers to how resistant a password is to being cracked or guessed—especially through brute-force attacks. Strong passwords are:
- Long (the more characters, the better)
- Complex (include letters, numbers, and symbols)
- Unpredictable (avoid dictionary words or personal info)
Examples of weak passwords:
password, 123456, qwerty, john1985, admin
Examples of strong passwords:
D#4p!e8zL2@r, fT7$gP!y9R&w
Features of the Online Password Generator
Our secure password generator offers full customization so you can generate passwords tailored to your security needs:
Ambiguous characters can make passwords harder to read and type, especially when copied by hand. You can choose to remove them for usability—just remember that reducing character options may slightly lower overall strength.
🔢 Understanding Password Entropy
Password entropy measures how unpredictable a password is. It's expressed in bits—the higher the entropy, the harder it is to crack.
For example:
- 80-bit entropy = Secure against most common brute-force attacks
- 100-bit entropy = Extremely secure, even with powerful computing
Each time you use the password generator, entropy is recalculated based on your selected options.
🛡️ How to Create a Strong Password
Follow these tips to ensure your passwords are secure:
🧠 How to Protect Your Passwords
Creating a strong password is just step one. To truly secure your accounts:
- 🚫Never share your passwords with others
- 🔁Don't reuse passwords across different sites
- 🔐Use a password manager to store and manage unique passwords
- 📅Change your passwords periodically, especially for sensitive accounts
- 💻Avoid saving passwords on public or shared devices
- 📝Don't write passwords down in unsecured locations (e.g., sticky notes, notes app)
For maximum security, combine strong passwords with two-factor authentication (2FA) wherever possible.

How to Use the Password Generator
Step 1: Set Your Password Length
Use the slider to select how long you want your password to be. The longer the password, the more secure it will be.
- 12-14 characters: Good for standard accounts
- 15-20 characters: Recommended for email and financial accounts
- 21+ characters: Maximum security for critical accounts
Step 2: Choose Character Types
Select which types of characters to include in your password:
- Lowercase letters (a-z): Basic characters that most passwords should include
- Uppercase letters (A-Z): Adds complexity and is required by many websites
- Numbers (0-9): Further increases password strength
- Symbols (!@#$%^&*): Significantly enhances security but may not be accepted by all systems
For maximum security, enable all character types. However, if you need to manually type this password frequently, you might want to limit the character types for easier entry.
Step 3: Configure Advanced Options
Fine-tune your password with these additional options:
- Exclude ambiguous characters: Removes characters that look similar (like I, l, 1, O, 0). Useful if you need to read or type the password manually.
- Exclude brackets: Removes brackets like <>()[], which some systems may have trouble with.
- No repeated characters: Ensures each character appears only once in the password. Note that this option limits the maximum password length to the number of available characters.
Step 4: Generate and Use Your Password
Once you've configured your options:
- Your password will be automatically generated and displayed in the password field.
- Check the strength indicator to ensure your password meets your security needs.
- Click the refresh button to generate a new password with the same settings.
- Click the copy button to copy the password to your clipboard.
- Paste the password where needed and store it securely (preferably in a password manager).
Password Strength Indicators:
- Very Weak: Easily cracked
- Weak: Vulnerable to attacks
- Medium: Adequate for low-risk accounts
- Strong: Good for most accounts
- Very Strong: Excellent for sensitive accounts
Understanding Password Entropy
Entropy is a measure of password unpredictability, shown in bits. Higher entropy means a more secure password:
| Entropy (bits) | Security Level | Example |
|---|---|---|
| Less than 40 | Very Weak | Short password with limited character types |
| 40-60 | Weak | 8 characters with mixed types |
| 60-80 | Medium | 12 characters with mixed types |
| 80-100 | Strong | 16 characters with all character types |
| 100+ | Very Strong | 20+ characters with all character types |
