Frequently asked questions
Will the QR code expire?
No. QR codes generated here are static — they encode the data directly, so they work forever and never depend on our servers.
Can I add a logo to my QR code?
Yes. The QR generator supports custom colors and logo overlays while keeping the code scannable.
Are the generated passwords actually secure?
Yes. Passwords use the browser's cryptographically secure random source (Web Crypto API), the same standard banks and password managers rely on.
Can I use these for commercial projects?
Yes — print them on packaging, use them in client deliverables, or embed UUIDs in production code. No attribution needed.
