Everyday use

Share your Wi-Fi. Keep the password off the conversation.

By QRNest editorial · Updated October 26, 2026

Use a guest network

For visitors, a separate guest network is a better choice than sharing the network used by your personal devices. Set it up in your router settings and check that a phone can connect before creating a code. A QR code does not add security to the underlying network.

Enter the details exactly

Network names and passwords are case-sensitive. Choose the matching security option: most password-protected networks use WPA/WPA2; an open network has no password. Hidden networks may need the hidden-network setting. QRNest escapes special characters in the Wi-Fi payload.

Treat the code like a password

Anyone who can photograph or scan the code may be able to join the network. Put it where intended guests can see it, rather than on a public social feed. The password is encoded, not encrypted. Do not assume the pattern keeps it secret.

Print, connect, and refresh

Test with a phone that is not already connected. Scan using its camera and confirm that the connection prompt names the right network. Support varies by device. If you change the network name or password, create a new code and replace the printed copy.
