This can be helpful on devices which have a display device but no keyboard to help users connect during first-time setup. Example: https://github.com/aderusha/HASwitchPlate/blob/master/Documentation/01_Arduino_Sketch.md#first-time-setup https://github.com/aderusha/HASwitchPlate/blob/master/Docume... For this project, on first boot the device creates an AP, then displays a QR code containing SSID and key (along with text version of the same) that the user can connect to. Upon connection a captive portal will redirect the user to the configuration page, allowing the user to select the desired SSD and configure other essential values. If you have a phone handy, just scan the display, accept the prompt to connect, and the next thing you see if the configuration page popping up as Apple and Android detect it as a login page.
