Best Practices for Signal QR Codes

Deploying Signal QR codes effectively requires balancing accessibility with operational security. Follow these proven strategies to maximize reach while maintaining the security advantages that make Signal valuable.

Security and Privacy Considerations

• •Phone Number Privacy: Signal requires phone numbers for registration but doesn't display them publicly. Consider using a dedicated number for public Signal QR codes to separate professional and personal communications.
• •Group Link Management: Signal group links can be disabled and regenerated in group settings if they become compromised or too widely distributed.
• •Verify Safety Numbers: For high-security contacts, verify safety numbers through secure channels after connecting via QR code to confirm no man-in-the-middle attacks.
• •Enable Registration Lock: Set a PIN and registration lock to prevent attackers from hijacking your Signal account even if they gain access to your phone number.
• •Public Display Risks: When displaying Signal QR codes publicly, expect unwanted messages. Consider using group moderators or clearly stating communication guidelines.

Design and Distribution Strategies

• •Clear Context and Instructions: Include text explaining what the QR code connects to (e.g., "Secure Signal messaging for tips" or "Join our encrypted community group").
• •Print Quality for Security: High-quality printing prevents scanning errors that could frustrate users trying to establish secure contact. Use vector SVG for professional printing.
• •Size for Discretion: Business cards need smaller codes (0.8x0.8 inches minimum), while public displays can use larger codes (4+ inches) for distance scanning.
• •Physical Security: In sensitive contexts, display QR codes where they can't be easily photographed by surveillance or replaced with malicious codes.
• •Multi-Channel Distribution: Share Signal QR codes across websites, social media, email signatures, and print materials to maximize accessibility.
