Question 1

Is this password generator free to use?

Accepted Answer

Yes, the Roughtools Password Generator is completely free with no hidden charges, subscriptions, or premium tiers. You can generate unlimited passwords of any length and complexity without creating an account. Roughtools is funded through non-intrusive advertising, which keeps every tool on the site permanently free for all users worldwide, whether you need one password or generate hundreds daily for a business.

Question 2

Do I need to create an account or sign up?

Accepted Answer

No account, sign-up, email address, or personal information is required at any stage. Open the page, configure your options, and your password is generated instantly in your browser. Nothing is transmitted to any server — all generation happens locally using your device's cryptographic hardware. There are no usage limits, no sessions, and no tracking of generated passwords.

Question 3

Is my generated password stored or sent anywhere?

Accepted Answer

No. Every password is generated entirely within your browser using the Web Cryptography API — specifically crypto.getRandomValues(), which is the browser's built-in cryptographically secure random number generator. Your passwords are never transmitted to Roughtools servers, logged, stored, or shared. Once you close the tab, the generated password is gone — we have no record of it.

Question 4

Does this password generator work on mobile and tablet?

Accepted Answer

Yes. The Password Generator is fully responsive and works on all modern smartphones and tablets running iOS 14+ or Android 8+. The touch-friendly interface supports all generation modes including Standard, Passphrase, and PIN. The copy-to-clipboard button works on mobile browsers. For iOS Safari, if copy does not work, simply tap the password field and use the standard iOS text selection to copy.

Question 5

Which browsers support this password generator?

Accepted Answer

The generator works in all modern browsers that support the Web Cryptography API: Google Chrome 37+, Mozilla Firefox 34+, Microsoft Edge 12+, Safari 11+, and Opera 24+. All current versions of these browsers are fully supported. The tool does not work in Internet Explorer, which lacks the crypto.getRandomValues API. For maximum security and compatibility, we recommend using the latest version of Chrome, Firefox, or Edge.

Question 6

How random and secure is the generated password?

Accepted Answer

Passwords are generated using crypto.getRandomValues(), the Web Cryptography API's cryptographically secure pseudorandom number generator (CSPRNG). Unlike Math.random() — which is predictable and unsuitable for security — crypto.getRandomValues() sources entropy from the operating system's secure random pool (equivalent to /dev/urandom on Linux or BCryptGenRandom on Windows). This is the same source used by password managers and security software. The entropy score displayed tells you exactly how mathematically unpredictable your password is.

Question 7

What is password entropy and what score should I aim for?

Accepted Answer

Password entropy is a measure of unpredictability expressed in bits. The higher the entropy, the longer a brute-force attack takes to crack the password. A 28-bit password can be cracked instantly; 60 bits requires years with current hardware; 80+ bits is effectively uncrackable with foreseeable computing power. For online account passwords, aim for 60+ bits (Strong). For encryption keys, database passwords, or master passwords, aim for 80+ bits (Very Strong or Excellent). The entropy score updates in real time as you adjust settings.

Question 8

How do I generate a strong password with this tool?

Accepted Answer

To generate a strong password: (1) Select "Standard" mode. (2) Set the length slider to at least 16 characters — longer is always better. (3) Enable uppercase, lowercase, digits, and symbols for maximum character variety. (4) Optionally toggle "Exclude Ambiguous Characters" to avoid 0, O, l, and 1 confusion. (5) Click the refresh icon or change any setting to generate a new password. (6) Click "Copy" and paste it directly into a password manager. Never reuse generated passwords across multiple accounts.

Question 9

Why should I use Roughtools instead of other password generators?

Accepted Answer

Roughtools Password Generator uses crypto.getRandomValues() for cryptographically secure generation — the same standard used by professional security tools. Unlike many online generators that use Math.random() (which is not cryptographically secure), or generators that transmit passwords to their servers for logging, this tool generates everything locally in your browser with no server communication whatsoever. It also provides entropy scoring, passphrase mode for memorable-yet-secure passwords, and PIN mode, all in a clean, ad-light interface with no registration required.

Question 10

How do I report a bug or suggest a new feature?

Accepted Answer

To report a bug or suggest a feature improvement for the Password Generator, use the feedback link in the site footer or visit the Roughtools contact page. When reporting a bug, please include: the browser name and version, operating system, what you were trying to do, and what happened instead. Feature requests such as new character sets, export options, or additional generation modes are reviewed regularly and the most-requested features are prioritised in development.
