How does a QR code connect to WiFi by itself?
Smartphone camera apps have a built-in feature that recognizes a standard-format string like "WIFI:S:name;T:security-type;P:password;;" embedded in a QR code, and automatically brings up the WiFi connection screen. This generator builds a QR code in exactly that standard format.
Is this information handled safely?
Yes, the WiFi name and password you enter are converted into a QR code entirely within your browser, and are never sent to or stored on a server. That said, the generated QR code image itself does contain the password information as-is, so be careful not to share it with anyone you don't trust.
Frequently Asked Questions
Will every smartphone be able to read it?
Most recent default iOS and Android camera apps will recognize it automatically. Some older devices may need a separate QR code scanning app.
How is this different from a regular QR code generator?
A regular QR code usually holds a URL or plain text, while this generator embeds the standard-format string for automatic WiFi connection, so the connection screen pops up the instant it's scanned.
