Create a QR Code to Share Your WiFi Password

A WiFi QR code encodes your network credentials in a standardized format that phones understand natively. When someone scans it with their camera app, the phone reads the network name, password, and encryption type, then offers to join the network automatically.

The code contains three pieces of information:

• SSID -- Your network name (e.g., "CoffeeShop_Guest")
• Password -- The exact password, case-sensitive
• Encryption type -- WPA/WPA2, WPA3, or WEP (most modern networks use WPA2 or WPA3)

There's also an option for hidden networks and open networks (no password), though those are less common.

The entire connection happens locally on the device. The QR code doesn't send data anywhere, it just passes the credentials to the phone's WiFi settings. Both iPhone (iOS 11 and later) and Android phones support this natively through the camera app.

Here's how to generate your WiFi QR code using MQRG:

1. Open MQRG on your iPhone or iPad and tap the + button.
2. Select "WiFi" as the QR code type.
3. Enter your network name (SSID) exactly as it appears in your WiFi settings, including capitalization and spaces.
4. Enter the password exactly as set on your router.
5. Select the encryption type -- Choose WPA/WPA2 for most networks. If you're not sure, check your router settings.
6. Customize and save -- Pick colors, add a label, then download or print.

Double-check the SSID and password before saving. A single typo means the code won't connect. Test it on your own phone first.

WiFi QR codes are useful anywhere guests need network access. Here are the most practical placements:

Cafes and restaurants: Print the QR code on table tents, near the register, or on the wall. It saves your staff from repeating the password all day and speeds up the customer experience.

Airbnb and vacation rentals: Include the WiFi QR code in your welcome guide, on a framed card near the router, or in your listing's check-in instructions. Guests arrive, scan, and they're connected. One less message in your inbox.

Offices and coworking spaces: Put the guest WiFi QR code in meeting rooms, the reception area, and conference spaces. Visitors connect without needing to ask, and you don't have to share the password verbally.

Home: Frame a small QR code near your entryway or on the fridge. When friends visit, point them to the code instead of dictating your password.

For WiFi QR codes, a static QR code is usually the right choice. Here's why: WiFi credentials are encoded directly in the code itself, so the phone reads them locally without visiting any URL. There's no internet connection needed to use a static WiFi QR code, which is the whole point since the person scanning doesn't have internet yet.

A smart QR code (dynamic QR code) works by redirecting through a URL, which means the scanner needs an internet connection to resolve the redirect. Since someone scanning your WiFi code probably isn't connected to the internet yet, a static code makes more sense here.

The one exception: if you change your WiFi password frequently (say, weekly for security at a coworking space), a smart QR code lets you update the destination without reprinting. The person would need mobile data to scan, but that's a reasonable tradeoff if you rotate passwords often.

A few practical tips to make sure your WiFi QR code works every time:

• Test before printing. Scan the code with your own phone (preferably a different device than the one you created it on) to confirm it connects.
• Update the code when you change your password. A WiFi QR code with the wrong password is worse than no QR code at all. If you change passwords, generate a new code immediately.
• Use a simple SSID. Network names with special characters can sometimes cause issues. Stick to letters, numbers, and basic punctuation.
• Print large enough. A 3 x 3 cm code works fine for table distance. For a wall sign, go bigger.
• Add a label. "Scan to connect to WiFi" is clear and tells people what to expect. Don't assume everyone knows what a QR code does.

If you operate a business with a guest network, keep the guest network separate from your internal one. Share the guest QR code publicly but keep your business network private.
