I am having a query that, can any one solve it.

There are multiple ESP8266, connected to the same wifi router, and if in case I have changed the password of the router, then all the esp8266 will be disconnected.

Is there any way to change the password of all the esp8266, without individually configuring with wifi-manger?

I have never tried WPS in the ESP but that may be another way?

Basically esp8266 will listen to WiFi signal and SmartConfig will broadcast the SSID + Pass.
