Usually these credentials are preloaded while coding.But here we explain a product prototype where SSID,PASSWORD,BOT TOKEN,ID all are fed through a web page and stored in EEPROM (Flash mem) of ESP32.

Note :
ESP32 does not have an internal EEPROM. However, the EEPROM library for ESP32 is actually using the NVS (FLASH Memory) of ESP32 under the hood to emulate the EEPROM functionality.
512bytes or even 4kB of Flash Memory (4MB) can be used by EEPROM library.
The EEPROM Library is currently deprecated and replaced by the Preferences library.
Use the new Preferences library that’s guaranteed to give you up to 20kB of FLASH space for EEPROM.
