Frequently Asked Questions
Is it secure to share JWTs via QR codes?
Only share non-sensitive JWTs via QR codes, and only in trusted environments. QR codes are easily scannable by anyone nearby. Never share production authentication tokens this way. Use for testing, demos, or public data only.
What's the maximum JWT size for QR codes?
QR codes become harder to scan as they get larger. We recommend keeping JWTs under 2,000 characters for reliable scanning. Larger tokens create very dense QR codes that may fail to scan properly, especially on mobile devices.
Why won't my phone camera scan the generated QR code?
Ensure good lighting, stable hands, and proper distance from the code. Very large or dense QR codes (from long JWTs) can be difficult to scan. Try increasing QR code size, improving image quality, or shortening your JWT payload for better scanning.
Can I scan QR codes from images or screenshots?
Yes! Our tool supports uploading QR code images from your device. You can scan from photos, screenshots, or saved images. This is useful when you receive QR codes via email, messaging apps, or other digital channels.
What mobile apps work best for scanning JWT QR codes?
Most modern smartphone cameras and QR scanner apps work well. iOS Camera app (iOS 11+), Google Lens, and dedicated QR scanner apps all work. Our web tool also provides camera-based scanning directly in your browser.
