How to Create a WiFi QR Code: Step-by-Step Guide to Sharing Your Wi-Fi Password (2026)

1. Before You Start: Find Your WiFi Network Details

Most failed WiFi QR codes come from one wrong character, so gather the exact credentials first. You need three pieces of information, and each one is case-sensitive:

• Network Name (SSID): The name your phone shows in its WiFi list. Copy it exactly, including capital letters, spaces, and symbols. If you have separate 2.4 GHz and 5 GHz names, pick the one guests should use.
• WiFi Password: The network key (sometimes called the WPA key or passphrase). It is often printed on a sticker on the router, but if you have ever changed it, check the router's admin page or app instead.
• Security Type: Look in the router's wireless settings. 'WPA2-Personal', 'WPA3-Personal' and 'WPA2/WPA3 mixed' all use the WPA option. Only very old equipment uses WEP. An open network has no password.
• Hidden or Visible: If your router does not broadcast the network name, note that the network is hidden. You will need to turn on the hidden network option when you create the code.

2. How to Make a QR Code for WiFi in TryQRMint (Step by Step)

WiFi QR codes are static, so they are free on TryQRMint. You can design and preview the code without an account, and you need a free account to save and download it. Here is the exact flow in the Studio:

• Step 1 — Pick the WiFi Access type: Open the free WiFi QR code generator, or choose 'WiFi Access' from the static types in the Studio.
• Step 2 — Enter your network details: Type the Network Name (SSID) and the password, then choose the security option: WPA/WPA2/WPA3, WEP, or No Password. Tick 'Hidden Network' only if your SSID is not broadcast.
• Step 3 — Customize the design: Pick dark-on-light colors, add a WiFi icon or your logo, and choose a frame with a short instruction such as 'Scan to join our WiFi'. Error correction is set automatically, and it switches to a higher level when you add a logo.
• Step 4 — Preview, sign in and save: Check the live preview, then sign in (or create a free account) and save the code to your dashboard.
• Step 5 — Download and test: Download a PNG from your dashboard. SVG is available during the 7-day trial and on Pro or Business plans. Before printing, scan the code with an iPhone and an Android phone and confirm that both connect.

3. What a WiFi QR Code Actually Contains

A WiFi QR code holds no link. It stores a short text string in a widely supported format, for example `WIFI:T:WPA;S:MyGuestWiFi;P:MyPassword;;`. The phone camera recognizes this format and offers to join the network. TryQRMint builds the string for you and escapes special characters such as semicolons, commas and colons in your network name or password, so these characters no longer cause the code to fail.

• T: The security type. WPA covers WPA, WPA2 and WPA3 personal networks, WEP is the legacy option, and nopass means an open network.
• S: The network name (SSID).
• P: The password. It is left out for open networks.
• H:true: This flag is added only when you mark the network as hidden.
• Not supported: Enterprise networks (WPA2/WPA3-Enterprise with 802.1X logins, RADIUS, or certificates) need more fields than this format offers, and TryQRMint does not support them.

4. Other Ways to Share WiFi with a QR Code (and When a Printed Code Is Better)

Recent phones can show a WiFi QR code on screen, which is handy for sharing with one person at a time:

5. Where to Place Your WiFi QR Code

Put the code where people first ask for the WiFi, and at a height they can reach comfortably with a phone:

• Home: A small framed card in the hallway or on the fridge, so you no longer need to read the password aloud.
• Vacation rentals: A welcome card next to the house manual. Our Airbnb WiFi QR code guide covers welcome card layouts and check-in messages.
• Cafes and small offices: Counter signs, table tents, or reception desks. This saves staff from answering the same question.
• Meeting rooms: A small sticker on the table or next to the screen, linked to the guest network only.

6. Printing and Sizing Tips

WiFi codes contain more data than a short URL, so they are a little denser. Keep these rules in mind:

• Size: For a card that people scan from about arm's length, a code around 3 cm (1.2 in) wide is a practical starting point. Go larger for wall signs, and always test a printed proof. See our QR code printing and sizing guide for distance-based sizing.
• Contrast: Use a dark code on a light background. Avoid light-on-dark inverted designs.
• Quiet zone: Leave a clear margin around the code. Do not let frames or text touch the modules.
• Glare: Use matte paper or anti-glare acrylic. Glossy glass under spotlights often blocks the scan.

7. Troubleshooting: WiFi QR Code Scans but Will Not Connect

If the camera reads the code but the phone fails to join, the cause is almost always in the credentials or the router, not the QR code itself:

• Wrong password or SSID: Check capitalization, extra spaces, and look-alike characters such as O and 0, or l and I.
• Wrong security type: Choosing WEP for a WPA2 or WPA3 network will fail. Use the WPA option for almost every modern router.
• Password changed: A static WiFi code can't be updated. Create and print a new one whenever you change the password.
• Guest network off or out of range: Confirm that the guest network is enabled and reaches the spot where the code is posted.
• Device-specific steps: Some Android cameras need Google Lens. Our guide on how to scan a WiFi QR code on iPhone and Android walks through each phone, and the full WiFi QR code troubleshooting guide covers router-side issues.
