Walkthrough
How to Create a Signal QR Code
Generate your Signal contact link
In Signal, go to Settings → Phone Number → Sharing → "Share Contact." It produces a signal.me link.
Paste here
The QR encodes the signal.me URL — no phone number visible to scanners.
Customize discreetly
Stay monochrome — flashy QR codes on a tip-line poster look suspicious.
Where it works
Signal QR Code Use Cases
Journalist tip-line posters at trade shows and press events — Signal's reputation lends credibility
Whistleblower-friendly job postings linking to a Signal group for vetted candidates
Conference badge ribbons for security researchers who want to chat without exchanging phone numbers
Field-staff onboarding posters in NGO offices for secure team communication
Speaker bios at privacy/cybersecurity events with Signal QR instead of WhatsApp or SMS
What works in practice
Signal QR Code Best Practices
Signal's contact links are tied to your phone number. If you change numbers, the link breaks and you'll need a new QR.
For group invites, the link expires when you toggle group access settings. Don't laminate it onto something permanent.
Even with Signal, the QR scan is logged in the user's browser/camera history. For maximum privacy, share the QR in person and direct messages.
Don't add UTM parameters to a Signal contact URL — Signal strips unrecognized params and may not parse the link correctly.
Signal Desktop also opens these links — useful if you're sharing to a colleague at a conference who's on a laptop.
