Reuse credentials across devices
If you are programming in arduino (or other c++ microcontrollers, I guess)
File with wifi credentials
Create this file in your library folder alongside your other libraries downloaded by arduino
library/credentials/wifiCredentials.h
#pragma once
const char* mySSID = "the name of your wifi network";
const char* myPASSWORD = "the password for your wifi network";
Create a new user in the user interface

and add its credentials to the file below
library/credentials/exampleCredentials.h
#pragma once
const char* offbeatIotUser= "the user you created in the browser";
const char* offbeatIotPassword= "the users password";
then, when importing the credentials file, the constants will be available in code
using user credentials in a separate header file
import exampleCredentials.h
....
webSocketClient.begin(host, 80, path);
webSocketClient.setExtraHeaders("Accept=application/json");
webSocketClient.setAuthorization(offbeatIotUser, offbeatIotPassword);
