Password Security Information

What Makes a Strong Password?

  • At least 12 characters in length
  • Includes a mix of uppercase and lowercase letters
  • Contains numbers and special characters
  • No personal information (names, birthdates)
  • Not a common word or phrase
  • Unique for each service or account

Understanding Password Entropy

Password entropy is a measure of password unpredictability, expressed in bits. Higher entropy means greater security. For general online accounts, aim for at least 60 bits, while sensitive accounts should have 80+ bits. Our entropy meter helps you visualize your password's resistance to brute force attacks.

Password Security Best Practices

  • Use a different password for each account
  • Consider using a password manager
  • Enable two-factor authentication when available
  • Change passwords periodically
  • Don't share your passwords with others
  • Be wary of phishing attempts requesting your password

Features at a Glance

  • Real-time Password Strength Entropy Calculation (bits)
  • Customizable Character Sets
  • Advanced Generation Options
  • Pattern-Based Password Generation
  • Memorable Passphrase Generation

Password Strength and Entropy Analysis

At the top of the tool, you’ll see a live evaluation of the password you generate:

✅ Password Strength Bar

  • Shows a rating from Weak to Very Strong.
  • Encourages creation of highly secure passwords.

✅ Entropy Measurement (bits)

  • Displays the password’s entropy in bits—a measure of unpredictability.

Categories include:

  1. Weak (28 bits)
  2. Moderate (60 bits)
  3. Strong (80 bits)
  4. Very Strong (100+ bits)
  5. Example shown in the screenshot: Entropy of 105.1 bits (Very Strong).

✅ Entropy Graph

  1. Visual bar chart comparing your current password to entropy categories.
  2. Helps you quickly see how secure your password is.

Random Password Generator

Adjustable Password Length

A simple slider lets you set the desired password length:

  • Range: Customize from short to long passwords.
  • Precision Input Box: Enter an exact length manually.
  • Longer passwords generally yield higher entropy and better security.

Strong Password Generator

Customizable Character Sets

You can tailor your password’s character composition with these toggles:

✅ Uppercase Letters (A-Z)
✅ Lowercase Letters (a-z)
✅ Numbers (0-9)
✅ Special Symbols (!@#$%^&*)

All these options can be turned on or off to match your specific needs. This flexibility ensures you meet requirements for different services or personal preferences.

Advanced Options

Your generator includes thoughtful toggles to refine the output:

Exclude Ambiguous Characters

  • Removes characters like 0/O, l/I to avoid confusion.

Exclude Similar Characters

  • Ensures visually similar characters aren’t used.

No Repeated Characters

  • Guarantees all characters are unique within the password.

✅ Custom Characters (Optional field)

  • Add specific characters you want to include.

This level of control is excellent for meeting complex security policies or personal preferences.

Generate Multiple Passwords

Below the character set options:

  • You can specify how many passwords to generate at once.
  • Great for creating multiple credentials quickly.

A single click on Generate produces the desired number of strong, randomized passwords.

Pattern-Based Generation

A standout feature in your tool is Pattern-Based Password Generation.

How It Works:

  • Define a custom pattern to control character types in each position.

Use these symbols:

a – Lowercase letter

A – Uppercase letter

9 – Digit

! – Special character

* – Any character

Example:

Pattern “AAaa99!!” might generate “TRge52&$”

This mode is perfect for:

  1. Enforcing specific password policies.
  2. Creating passwords with predictable but secure structures.
  3. Meeting organizational compliance requirements.

Your users simply type the pattern they want, click Generate from Pattern, and get a password matching the exact structure they need.

Memorable Passphrase Generator

Your tool doesn’t just do complex passwords—it also supports human-friendly passphrases:

✅ Number of Words

  • Choose how many dictionary words (e.g., 4, 5, 6) to include.
  • Longer phrases mean higher entropy.

✅ Word Separator Options

  • Hyphen (-), space, underscore (_), etc.
  • Customize to taste or platform requirements.

✅ Extra Options:

  • Capitalize Each Word – Increases readability.
  • Include Numbers – Adds digits for more complexity.
  • Include Symbols – Boosts entropy with special characters.

✅ Example Output:

correct-horse-battery-staple

This option is ideal for:

  • Easier memorization.
  • Security without sacrificing usability.
  • Passwords for vaults, master passwords, or any login you want to remember easily.

FAQs on Password Generator

Q1. What is a password generator?

A password generator is an online tool that creates strong, random passwords or passphrases for you, making it easy to improve your online security and avoid predictable passwords.

Q2. How does your password generator measure password strength?

It uses a real-time strength meter and entropy calculation (in bits) to show how hard your password is to guess or crack, with ratings from Weak to Very Strong.

Q3. Can I customize the characters in my password?

Yes! You can include or exclude uppercase letters, lowercase letters, numbers, and special symbols. You can also exclude ambiguous or similar characters for clarity.

Q4. What is entropy in passwords?

Entropy measures password unpredictability in bits. Higher entropy means greater resistance to brute-force attacks. Our generator displays your password’s entropy to help you choose a secure one.

Q5. What is pattern-based password generation?

It lets you define a custom structure using symbols (e.g., A for uppercase, 9 for digit, ! for special character) to create passwords that meet specific policy requirements.

Q6. What is a passphrase?

A passphrase is a sequence of words (like “correct-horse-battery-staple”) that is easier to remember but still very secure. Our password generator can create customizable passphrases with chosen word count and separators.

Q7. Can I generate multiple passwords at once?

Yes. You can choose to generate several passwords in one go, saving time if you need multiple secure credentials.

Q8. Is this password generator free to use?

Yes, it’s completely free. You can use all its features without any cost.

Q9. Why should I use a password generator?

It helps you avoid weak or reused passwords by creating unique, random, and strong passwords tailored to your needs, significantly improving your online security.

Q10. Is the password generator secure?

Our password generator runs in your browser, so your generated passwords aren’t sent anywhere. You stay in control of your security at all times.
