 Make some sketches for erasing the EEPROM area, or some erasing utility is needed. You can prepare the sketch to erase the saved credential with *AutoConnectCredential*. The *AutoConnectCrendential* class provides the access method to the saved credential in EEPROM and library source file is including it.
