About WiFi QR Code

A WiFi QR code encodes the network name (SSID), password, and security type in a format every major phone understands natively. iOS 11+ and Android 10+ recognise WIFI: codes, show a "connect to [network]" prompt, and join without the user ever typing a password. It's the friction-free replacement for "ask the barista for the WiFi password" or pinning a password to a kitchen whiteboard. The encoded string follows a semi-standardised format: WIFI:T:<auth-type>;S:<ssid>;P:<password>;H:<hidden>;; where auth-type is WPA, WPA2, WEP, or nopass (for open networks). Escape reserved characters (backslash, semicolon, comma, colon, quotes) with a backslash if they appear in your SSID or password. Hidden networks need H:true and the SSID passed explicitly, since the phone can't discover the network by broadcasting. Typical placements: framed poster near a coffee-shop counter, sticker on the back of a guest bedroom door in a rental, under the desk in a shared coworking space, on the WiFi router itself for household members. Security note: anyone who can see the printed QR code has your password, so don't post it in public-facing spaces for a network that also has access to sensitive LAN resources. For guest networks (isolated from internal traffic), the convenience usually outweighs the risk.

Frequently Asked Questions

What goes in the WIFI: string exactly?

WIFI:T:WPA;S:MyNetwork;P:MyPassword;;. T = security type (WPA, WPA2, WEP, or nopass). S = SSID. P = password. H = hidden (optional, true/false). Escape backslash, semicolon, comma, and colon with a backslash inside SSID or password values.

Does iOS support WiFi QR codes natively?

Yes, since iOS 11 (2017). Point the camera at the code, tap the notification banner, and iOS joins the network — no password typed. Android 10+ supports the same format. Older Android versions need a dedicated scanner app.

Is a WiFi QR code less secure than typing the password?

Functionally identical — the password is the same either way, just transferred differently. The risk shifts: instead of the password being written down on a sticky note, it's printed in a QR. Anyone who can photograph or scan the code has the password. For guest networks (isolated LAN), convenience wins.

Can I make a QR code for a hidden network?

Yes — set H:true in the WIFI: string. The phone can't auto-discover the SSID, so the QR code supplies the network name explicitly and the phone joins directly. Without the H:true flag, the phone scans visible networks first and fails to find a hidden one.
