#84829 Hello everyone...

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?

#84844 You would need to add some sort of command within the ESP code to tell them to change the password. But you would have to be careful of security issues.

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

#84952 There is a mechanism that allows you to reconfigure WiFi credentials even when the device is disconnected. It's called SmartConfig.

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