What Is a WiFi QR Code?

A WiFi QR code is a scannable 2D barcode that embeds your Network ID (SSID), Password, and Encryption Type. When scanned with a smartphone camera, it automatically connects the device to your wireless network without requiring the user to type the password manually.

Sharing your WiFi password is a pain. You have to hunt for the sticky note on the back of the router, read out a long string of random characters, and hope your guest types it correctly. The WiFi QR Code solves this instantly.

How Do You Create a Free WiFi QR Code?

Creating your secure client-side WiFi QR code takes less than 30 seconds. Follow these steps to generate your code:

  1. Find your Network Details: Locate your exact Network Name (SSID) and Password. Look on the back of your router if you do not know them.
  2. Select your Encryption Type: Choose WPA/WPA2 (most common for modern routers), WEP (older), or Unencrypted (for open guest networks).
  3. Enter the Information: Type your exact SSID and password into our generator above. Note that these fields are case-sensitive.
  4. Check the Hidden Network box (if applicable): If your router does not broadcast its network name, tick the "Hidden Network" box.
  5. Download your Code: Click to download the code as a transparent PNG for digital sharing, or vector SVG for high-quality printing.

How Do You Find Your Network Details?

To create your code, you need accurate details. If you do not have them memorized, here is how to find your SSID and password on your current device:

Windows:

  • Click the WiFi icon in the taskbar.
  • Right-click your connected network and select Properties.
  • Scroll down to see the "SSID" (Network Name).

Mac:

  • Hold the Option key and click the WiFi icon in the menu bar.
  • Your SSID and Security type (usually WPA2 Personal) will be listed.

iPhone:

  • Go to Settings → Wi-Fi.
  • Tap the (i) icon next to your connected network to see its name (SSID).
  • To view the password, tap Password and authenticate. Available on iOS 16 and later.

Android:

  • Go to Settings → Network & Internet → Wi-Fi.
  • Tap your connected network, then tap the Share icon (QR icon or lock icon).
  • Your phone will display a QR code and the password as plain text nearby.

Is It Safe to Share WiFi via QR Code?

Yes, sharing your WiFi credentials via QR code is often safer than the alternative methods. Our generator specifically uses client-side encryption, meaning your password never leaves your browser.

Here are three reasons why it is secure:

  • No Verbal Sharing: You do not have to shout your password across the room or write it on a piece of paper that can be lost or stolen by bad actors.
  • Client-Side Encryption: Our generator runs entirely in your browser. Your password is never sent to our servers. It is strictly converted to the QR image directly on your device. For more on web security standards, consult the W3C Web Security guidelines.
  • WPA/WPA2 Support: We support the standard security protocols used by 99% of modern routers, approved by the Wi-Fi Alliance.

What Are the Best Practices for Restaurants and Businesses?

If you run a cafe, hotel, or retail store, offering a WiFi QR code improves customer satisfaction. Guests connect faster, and your staff will not be repeatedly asked for the password.

  • Separate Guest Network: For security, always create a "Guest" network on your router that is separate from your internal business systems (POS, office computers). Create the QR code exclusively for this Guest network.
  • Print it Big and Clear: Place it on every table, menu, or at the register. See our QR Code Printing Guide for recommended sizes and material choices.
  • Laminate It: Protect the QR codes from spills, fading, and smudges to ensure they remain scannable for months.

What Is the Technical Format of a WiFi QR Code?

Under the hood, a WiFi QR code encodes a standard WIFI: URI string. Knowing this helps you understand how your phone reads the data.

The standard format looks like this:

WIFI:S:NetworkName;T:WPA;P:YourPassword;;

Where S: is the SSID (network name), T: is the encryption type (WPA, WPA2, or nopass for open networks), and P: is the password. Our generator builds this automatically - no manual formatting required.

We Tested This

Our team generated WiFi QR codes for three different network types: WPA2 home networks, open public hotspots, and enterprise WPA2-Enterprise networks. We tested each code on an iPhone 15 (iOS 17 native camera), a Samsung Galaxy S23 (Android 14), and a Google Pixel 7a. All codes decoded and connected in under 1 second on WPA2 networks. Open network codes connected immediately with no password prompt, as expected. WPA2-Enterprise is not supported by the WiFi QR standard — we confirmed the generator accurately declines to generate these and explains the limitation.

Frequently Asked Questions

Simple answers to common questions about this tool.

Yes! WiFi QR codes work on virtually all smartphones made after 2018. iPhones (iOS 11+) and Android phones (Android 10+) can scan WiFi QR codes directly with their built-in camera app-no special app needed. Older phones might need a third-party QR scanner app, but the QR code itself will still work.

For businesses, we recommend creating a separate guest network with a different password than your main business network. This keeps your sensitive devices (POS systems, computers, security cameras) on a separate, more secure network. For home use, it's generally safe, but you can always change your password periodically and generate a new QR code.

No-static QR codes are permanent. If you change your WiFi password, you'll need to generate a new QR code with the updated password. The good news? It only takes 30 seconds to create a new one with our tool! Just enter your new password, download, and replace your old printed codes.

No problem! Our generator handles all special characters including !, @, #, $, %, &, *, and more. Just type your password exactly as it is, and we'll encode it correctly into the QR code. This is actually one of the biggest advantages of WiFi QR codes-guests don't have to hunt for special characters on their keyboard!

It's super easy! On iPhone: Open your Camera app, point it at the QR code, and a notification will pop up saying 'Join [Network Name]'-just tap it. On Android: Open your Camera app or pull down the notification shade and tap the QR scanner icon, point at the code, and tap 'Connect to Network.' No app download needed!

Only if all locations have the exact same network name (SSID) and password. If each location has different WiFi credentials, you'll need to create separate QR codes for each location. This is common for chain restaurants or hotels-each location gets its own unique QR code.

For table tents or wall signs viewed from 1-2 feet away, print at least 5cm x 5cm (2 inches). For posters or signs viewed from across a room, go bigger-10-15cm (4-6 inches). The rule of thumb: your QR code should be at least 10% of the distance people will scan it from. When in doubt, go bigger!

Check these common issues: 1) Make sure you entered your password correctly (it's case-sensitive!). 2) Verify you selected the right security type (WPA2 is most common). 3) Ensure your network name (SSID) is exactly right. 4) Check that the printed code isn't too small or low-contrast. 5) Make sure the code isn't damaged, smudged, or wrinkled. If it still doesn't work, try generating a new code.

Our static QR codes don't track scans (privacy!), but you can check your WiFi router's admin panel to see how many devices are currently connected to your network. Most routers show a list of connected devices with connection times. This gives you a rough idea of usage without compromising anyone's privacy.

Only if they have different network names (SSIDs). Many routers broadcast both frequencies under the same network name, and devices automatically choose the best one-in this case, one QR code works for both. If your 2.4GHz and 5GHz networks have different names (like 'MyWiFi' and 'MyWiFi-5G'), you'll need separate QR codes for each.
