If any one of these two credentials is compromised, it needs to be identified and requires immediate action. OTAinfo library empowers the IoT device for taking actions locally. IoT device can identify the compromise, apply necessary control to maintain basic functionality and reverse the impact by taking appropriate actions promptly.
