How to use this WiFi QR Code Generator
Make a scannable WiFi login code for guests, customers, or your home. Your network name and password are processed locally in this browser tab. There is no account, software installation, or generate button to wait for: the preview updates whenever you change a field.
- Enter the network name exactly as it appears in the device WiFi list, including capitalization and spaces.
- Choose WPA/WPA2/WPA3-compatible WPA mode, WEP, or No password, then enter the matching password when required.
- Enable Hidden network only when the router does not broadcast its SSID. Adjust the design and check the preview.
- Download the code, print or display it, and test with a phone that is not already connected to that network.
Practical ways to use it
A QR code is most useful when it connects a physical item to one clear next action. Choose a situation where scanning genuinely saves time, and place a short visible instruction beside it.
- Place a small code at a guest-house reception desk so visitors can join without reading a long password aloud.
- Put a table card in a café, salon, waiting room, or coworking space to reduce repetitive support requests.
- Print one for a home office, rental property, classroom, or temporary event where separate guest access is available.
- Include a hidden-network flag when your own devices need to discover a non-broadcast SSID.
Important quality and safety notes
- Anyone who can scan the code may be able to recover and share its network credentials. Use a guest network rather than your primary administrative network.
- Special characters such as semicolons, commas, colons, quotes, and backslashes are escaped automatically. Do not manually add escape characters.
- WPA is the appropriate setting for most modern WPA2 and WPA3 personal networks. Enterprise networks requiring a username and certificate are not supported by this simple format.
- WEP is insecure and retained only for old equipment. For a new setup, choose modern router security and rotate the password if a printed code is exposed.
A final check before printing or publishing
Test the exported file, not only the browser preview. Place the actual PNG or SVG in the final layout, reproduce it at the intended size, and try more than one phone. Keep an unbroken quiet zone around the symbol and never crop, stretch, or cover its modules. Strong, consistent dark-on-light contrast is usually the safest choice.
This tool creates static QR codes: the content is stored directly in the pattern, with no scan analytics and no remote editing after download. Encode only information you are entitled to publish. In particular, anyone with the image may decode WiFi credentials, contact details, or pre-filled messages. Local generation reduces transmission for sensitive drafts, but a publicly displayed QR image is not a secret.
Frequently asked questions
Is my WiFi password sent to NightNote?
No. Password handling and QR rendering happen locally in your browser. Avoid sharing screenshots or downloaded codes if you want to keep the credentials private.
Which encryption option should I use?
Choose WPA for most current home and small-business routers, including common WPA2 personal networks. Select WEP only for legacy hardware, or No password for an open network.
Can guests connect without typing the password?
On phones and systems that support the WIFI QR format, scanning opens a network-join prompt. Behavior varies by operating system, so always test with your intended devices.
What does the Hidden network option do?
It adds H:true to the WIFI payload, telling compatible scanners that the SSID is not broadcast. It does not hide a network or improve security by itself.
Can I use this for an enterprise WiFi network?
This tool creates the common SSID-and-password format only. Enterprise 802.1X networks with certificates or individual usernames need a different configuration.
How do I revoke access after sharing a printed code?
Change the WiFi password or disable that guest network in your router. The old printed code cannot be remotely deactivated, so replace it with a new one.
