⚙️ How It Works
Use the sliders and checkboxes to configure your desired password length and required character types. Click 'Generate' to create a new secure string. The visual entropy bar instantly displays its relative cryptographic strength.
❓ Frequently Asked Questions
How secure are these generated passwords?
Extremely secure. Unlike simple math tools, this generator requests randomness directly from your operating system using `crypto.getRandomValues()`, ensuring the generated output is not mathematically predictable.
What does 'password entropy' mean?
Entropy is a technical measurement of a password's randomness, calculated in bits. The higher the entropy score, the harder the password is for a computer to crack via brute force. 80+ bits generally indicates a very strong password.
Is my new password saved anywhere on your servers?
No. The entire generation process executes securely inside your web browser. No data leaves your machine, making it fundamentally impossible for us to know or save the password you create.
Does the Password Generator work offline?
Yes, the Password Generator is fully functional offline. Because this tool runs entirely in your browser, no data is ever uploaded to external servers. Once the page is loaded, you can seamlessly continue using it without an active internet connection. You can also install Knicknaks as a Progressive Web App (PWA) for native-like offline access.
