Frequently Asked Questions
Is the 2fa QR Code Generator generator free?
Yes, completely free with no sign-up, no watermark, and no limits. Generate as many QR codes as you need.
Do QR codes created here expire?
No. Our QR codes are static — the data is encoded directly in the code. They work as long as the linked content exists.
Can I change the colours of my QR code?
Yes. Use the customisation options to change the dot colour, background colour, dot shape, and corner shape. Ensure sufficient contrast for reliable scanning.
What is the best size for printing a QR code?
Minimum 2cm x 2cm (about 0.8 inches) for close-range scanning. For posters or signs viewed from a distance, increase the size proportionally. A rough rule: 1cm of QR code for every 10cm of scanning distance.
