What commenters say

• Some users find the iOS share password functionality to be a more convenient solution for guest WiFi access.
• The QR code method has similar friction to the share password method, but offers asynchronous access without needing someone else's assistance.
• There are concerns about the security and potential for data exfiltration when using the tool, particularly if it is not run in a sandboxed environment.
• Running the tool in a private browser window or with network connectivity disabled can mitigate some of these security concerns.
• Some users prefer not to trim whitespace from WiFi SSIDs, as this can cause issues with certain networks.
• The lack of native QR code scanning support on most Android devices is seen as a limitation.
• There is a desire for browser permissions to include network access controls, similar to those for camera or location access.
