FAQ
Does a Wi-Fi QR send my password to DevNestro?
No. The network name and password stay in the browser while the code is drawn.
What does error correction do?
Higher levels still scan if part of the code is covered or damaged, but the symbol is denser.
Read the original guide: Put the URL, Wi-Fi, or message in a code people can scan.
