General Questions

• help_outline What is Password Generator Pro?

  Password Generator Pro is a free online tool that creates strong, random passwords to help you secure your accounts. Our generator offers various customization options to create passwords that meet specific requirements while maintaining high security standards.

• help_outline Why should I use a password generator?

  Human-created passwords are often predictable and vulnerable to various attacks. They frequently contain personal information or follow common patterns that hackers can easily guess. A password generator creates truly random, complex passwords that are significantly more difficult to crack.

• help_outline Is Password Generator Pro completely free?

  Yes! Password Generator Pro is 100% free to use with no limitations. We don't have premium features or hidden costs. Our mission is to make strong password creation accessible to everyone as a basic security measure.

• help_outline Do I need to create an account to use this tool?

  No account or registration is required. You can start generating secure passwords immediately without providing any personal information.

• help_outline What languages does the password generator support?

  Password Generator Pro is available in English, Spanish, French, Japanese, Portuguese, and Turkish. You can easily switch between languages using the language selector in the site footer.

Security Questions

• security Are the passwords generated truly secure?

  Yes. Our password generator uses cryptographically secure random number generation to create passwords that are unpredictable and resistant to brute force attacks, dictionary attacks, and pattern analysis. The passwords have high entropy, making them extremely difficult to crack.

• security Are my generated passwords stored anywhere?

  No. All password generation happens entirely in your browser (client-side). Your passwords are never transmitted to our servers, stored in databases, or logged in any way. Once you leave the page or close your browser, there's no record of the passwords you've generated.

• security How do I know my passwords aren't being intercepted?

  Our site uses HTTPS encryption to secure all communication between your browser and our server. Additionally, the actual password generation happens locally in your browser, so the generated passwords are never sent over the internet. You can even use our tool offline once the page has loaded.

• security What makes a password "strong"?

  A strong password typically has the following characteristics:

  • Length of at least 12 characters (longer is better)
  • A mix of uppercase and lowercase letters
  • Numbers and special characters
  • No recognizable words or patterns
  • No personal information (birthdays, names, etc.)
  • Uniqueness (not reused across multiple accounts)
• security How accurate is the password strength meter?

  Our strength meter evaluates several factors including password length, character variety, and complexity. While no strength meter can be 100% accurate (as it cannot account for all possible attack vectors), ours provides a good estimation based on current security standards and best practices. The meter analyzes entropy and resistance to common attack methods.

Using the Tool

• build How do I generate a password?

  Simply visit our home page and click the "Generate Password" button. You'll instantly get a secure password based on the current settings. You can adjust options like length and character types before clicking the button again to create a new password with your preferred settings.

• build What does "Exclude Similar Characters" mean?

  This option removes characters that look similar and can be confused with each other, such as:

  • The lowercase "l" and uppercase "I" (which can look like the number "1")
  • The uppercase "O" and the number "0"
  • Other visually similar characters

  This makes passwords easier to read and type correctly, especially in situations where you might need to manually enter the password from a separate device or written copy.

• build What does "Exclude Ambiguous Symbols" mean?

  This option removes symbols that might cause problems in certain contexts, such as:

  • Curly braces { }, brackets [ ], and parentheses ( )
  • Forward slash / and backslash \
  • Angle brackets < >
  • Other symbols that might be interpreted as code or have special meanings in programming contexts

  This is useful if you're creating passwords for systems that might have restrictions on certain special characters.

• build How do I copy the generated password?

  Click the "Copy" button next to the generated password. This will copy the password to your device's clipboard, allowing you to paste it wherever you need. A confirmation message will appear when the password has been successfully copied.

• build What password length should I choose?

  We recommend:

  • 12-14 characters for standard accounts (email, social media, etc.)
  • 16+ characters for important accounts (banking, primary email)
  • 20+ characters for critical security applications or when maximum security is required

  Longer passwords are generally more secure, but some websites have maximum length restrictions. Our tool allows generation of passwords between 4 and 64 characters to accommodate various requirements.

Technical Questions

• code How does the password generation algorithm work?

  Our password generator uses cryptographically secure pseudo-random number generation (CSPRNG) functions available in modern browsers. Specifically:

  • Server-side: We use PHP's random_int() function which provides cryptographically secure random integers
  • Client-side (fallback): We use JavaScript's crypto.getRandomValues() API which provides cryptographically secure random values

  These functions ensure high-entropy randomness suitable for security applications, unlike standard random number generators which may have predictable patterns.

• code Does the tool use cookies or track my data?

  We use only one functional cookie to remember your language preference. We do not use tracking cookies or analytics that collect personal data. No information about your password preferences or generated passwords is ever stored.

• code Can I use Password Generator Pro offline?

  Yes, once you've loaded our website, the password generator will continue to function even if you lose internet connectivity. This is because all the necessary code is downloaded to your browser when you first load the page, and the generation happens entirely client-side.

• code Are there API endpoints for integrating with other applications?

  Currently, we don't offer public API endpoints for integration. This is by design to maintain our focus on client-side security and privacy. If you need password generation functionality in your own application, we recommend implementing similar cryptographically secure generation methods directly in your code.

• code What technologies does Password Generator Pro use?

  Our password generator is built using:

  • PHP for server-side processing
  • JavaScript for client-side functionality
  • Materialize CSS framework for the user interface
  • HTTPS/TLS for secure communication
  • HTML5 and CSS3 for responsive design
