Question 1

What makes a password secure?

Accepted Answer

Secure passwords are long (12+ characters), random, and use a mix of uppercase, lowercase, numbers, and special characters. They avoid dictionary words, personal information, and common patterns. The most important factor is length - each additional character exponentially increases the time needed to crack the password. Learn more about creating secure passwords.

Question 2

How does this password generator work?

Accepted Answer

This tool uses the browser's cryptographically secure random number generator (crypto.getRandomValues()) to generate truly random passwords. Unlike Math.random(), this method is suitable for security-critical applications. All generation happens in your browser - passwords are never sent to any server.

Question 3

Is it safe to use an online password generator?

Accepted Answer

Yes, when the generator runs entirely client-side like this one. Our tool generates passwords using browser cryptographic APIs and never transmits passwords over the network. You can verify this by using browser developer tools or generating passwords while offline. For maximum security, use a trusted password manager with built-in generation.

Question 4

How long should my password be?

Accepted Answer

Minimum 12 characters for general accounts, 16+ for sensitive accounts (email, banking, work), and 20+ for master passwords (password manager, encryption keys). Length is more important than complexity - "correct horse battery staple" is stronger than "P@ssw0rd" despite using only lowercase letters and spaces. Read our 2025 password length recommendations.

Question 5

Should I use special characters in passwords?

Accepted Answer

Yes, when allowed. Special characters increase the "alphabet size" of your password, making brute-force attacks harder. However, prioritize length over complexity. A 16-character password with only letters and numbers is stronger than an 8-character password with all character types. Some sites restrict special characters, so use what's allowed. See the 2025 NIST guidelines on special characters.

Question 6

How does this compare to antivirus password generators?

Accepted Answer

Many antivirus suites (Avast, Norton, Kaspersky, Bitdefender) include password generators and managers. Our generator offers comparable cryptographic strength using the same secure random APIs, but runs entirely in your browser without requiring software installation. Both approaches use CSPRNG (cryptographically secure pseudo-random number generators). The key advantage here is privacy: nothing is installed, no account needed, and passwords never leave your device.

Question 7

What is the best free password generator?

Accepted Answer

The best free password generators use crypto.getRandomValues() (not Math.random()), run client-side, and don't require account signup. Options include: browser built-in generators (Chrome, Firefox, Safari), password manager generators (Bitwarden free tier, KeePass), and dedicated web tools like ours. Avoid generators that require email signup, show ads before revealing passwords, or don't clearly state they're client-side.

Question 8

Can I use this generator offline?

Accepted Answer

Yes! After the page loads, you can disconnect from the internet and continue generating passwords. This is possible because all password generation happens in your browser using local JavaScript and the crypto.getRandomValues() API. Try it: load this page, turn off WiFi, then generate passwords - they'll work perfectly, proving no server communication is needed. Compare password managers vs memorizing passwords.
