Someone shared a WiFi QR code with you. You scan it and your phone connects just fine. But now you need the actual password to connect another device, like a laptop, a smart TV or a friend’s phone.
The problem is that scanning a QR code just connects you automatically. It does not show you the password anywhere.
The good news is there is a simple way to decode a WiFi QR code and pull out the actual network name and password. You do not need an app, you do not need to be technical, and it takes about 20 seconds.
Why Does a WiFi QR Code Hide the Password?
A WiFi QR code stores your network details in a special format that your phone reads automatically. When you scan it, your phone connects without showing you what is inside the code.
But all that information is still there, including the network name (SSID) and the password. You just need a tool that can decode it and display the raw data instead of connecting automatically.
That is exactly what the free online scanner below does.
How to Get the WiFi Password from a QR Code
This method works whether your WiFi QR code is saved as an image, printed on a card, or displayed on a screen.
Step 1: Get the QR code as an image
First you need the WiFi QR code saved as an image file. Here is how to do that based on where your QR code is right now:
- Already saved on your phone: You are good to go, move to Step 2
- Printed on a card or sticker: Take a photo of it with your phone camera and save it
- On your laptop or PC screen: Press
Windows + Shift + Son Windows orShift + Command + 4on Mac to screenshot just the QR code area - Someone sent it to you on WhatsApp or email: Save the image to your phone or computer first
Step 2: Open the free QR code scanner
Open your browser and go to thestackanalyst.com/free-qr-code-scanner-online. This works on any browser including Chrome, Safari and Firefox. No account, no signup, nothing to install.
Step 3: Upload the QR code image
Tap or click the Upload button and select the QR code image from your device. The scanner accepts JPG, PNG and WebP formats which covers every standard photo or screenshot.
Step 4: Read the decoded result
The scanner reads the QR code and shows you the decoded content. For a WiFi QR code you will see something like this:
- Network name (SSID): MyHomeWiFi
- Password: mysecretpassword123
- Security type: WPA2
Now you have the actual password and can type it in on any device you want to connect.
Tip: If the result does not appear on the first try, crop your image so the QR code fills most of the frame and upload it again. This fixes most failed scans.
How to Do This on a Phone
If you are on your phone and want to read the WiFi password from a QR code, the steps are the same but here is exactly what to tap:
On iPhone:
- Make sure the QR code image is saved in your Photos app
- Open Safari and go to thestackanalyst.com/free-qr-code-scanner-online
- Tap Upload and select the image from your camera roll
- The WiFi password appears on screen
On Android:
- Make sure the QR code image is saved in your gallery

How to Do This on a Laptop or PC
If the WiFi QR code is on your laptop screen or saved on your computer, here is what to do:
- Take a screenshot of the QR code area using
Windows + Shift + Son Windows orShift + Command + 4on Mac - Open a new browser tab and go to thestackanalyst.com/free-qr-code-scanner-online
- Click Upload and select the screenshot
- The WiFi network name and password appear on screen
Once you have the password, you can type it manually into any device that cannot scan QR codes, like a smart TV, a gaming console or an older laptop.
Common Situations Where This Comes in Handy
Here are the situations where people most often need to decode a WiFi QR code:
- Connecting a laptop to WiFi: You scanned the QR code on your phone but your laptop needs the actual password to connect
- Smart TV or gaming console: These devices usually cannot scan QR codes so you need to type the password in manually
- Sharing WiFi with a guest: Someone asks for your WiFi password but you only have a QR code and cannot remember the password
- Setting up a new device: You got a new phone or tablet and need the password to connect it
- Router reset: Your router was reset and you need to find the original password stored in an old QR code image

Frequently Asked Questions
Can I get the WiFi password from a QR code without any app?
Yes. Upload the QR code image to thestackanalyst.com/free-qr-code-scanner-online and the password appears in the decoded result. No app needed at any point.
Does this work on a printed WiFi QR code?
Yes. Take a clear photo of the printed QR code with your phone camera, then upload that photo to the online scanner. Make sure the image is in focus and well lit for the best result.
What if the QR code only connects my phone but does not show the password?
That is normal. QR code scanning through your phone camera is designed to connect automatically without showing the details. To see the actual password you need to decode the image through the online scanner instead.
Is it safe to put a WiFi QR code image through an online scanner?
Yes, as long as you use a trusted tool. The Stack Analyst scanner processes your image in the browser and does not store it on any server. Your WiFi details stay private.
Can I use this to find a WiFi password I forgot?
Yes, if you have the QR code image saved somewhere. Take a screenshot or photo of the QR code and upload it. The decoded result will show you the password that was originally set when the QR code was created.
What does the decoded WiFi result look like?
It usually shows the network name, the password and the security type in plain text. For example: WIFI:S:MyNetwork;T:WPA;P:mypassword123. The scanner breaks this down into readable fields so you can easily copy the password.
