Easiest way for a person to set Wifi SSID and password without connecting to co puter?

Imagine I made a product and the rpi needs wifi, is there some rest way for the customer to set the SSID and password without hooking up mouse, kb and screen? I guess I could include a touch screen but 8 so t want to do that just for that purpose.

I guess if it broadcasts it’s own wifi for setup purposes and you had a simple http page that could allow them to configure the wpa_supplicant file and put in new wifi details. If it fails to connect after a few attempts it goes back into “setup mode” broadcasting its own wifi again…

And it is called "WiFi manager" and I use similar technology with small embedded devices.
