What is a password-protected QR code?
A password-protected QR code encrypts your text content using AES-256-GCM encryption. When someone scans the QR code, they must enter the correct password to view the content. We offer two modes: Offline mode (encrypted data stored in URL, no server needed) and Online mode (stored on server with expiry dates and view limits).
How secure is the password-protected QR code encryption?
Our password-protected QR codes use AES-256-GCM encryption, which is military-grade encryption used by governments and financial institutions worldwide. Your password is never stored in plain text - we use bcrypt hashing for online mode. Even if someone intercepts the QR code, they cannot read the content without the password.
What's the difference between offline and online encrypted QR codes?
Offline mode: Encrypted data is embedded directly in the QR code URL. No server storage needed, works forever, but limited to ~500 characters. Online mode: Content stored securely on our server with options for expiry dates (1 hour to 1 year), view limits (1 to 1000 views), and supports up to 5000 characters.
