Locking Android devices with Lock Screen Pin is an important part of security policy for any mobile enterprise or organizations with mobile workforce. Ensuring a strict Lock Pin policy enables these organizations to secure the devices from any intentional threats to sensitive data, information and settings.
Some of these security policies get stricter when they demand periodic change of device Lock PIN for enhanced security reasons. This may sound feasible and sensible if you have the devices physically with you to manually change the Lock Pins, and if we are talking about a handful of devices.
If your device is locked down with SureLock with capability to receive SMS and has internet connectivity, with the inbuilt SMS Command feature, you can set a new Lock Pin or change an existing one through SMS. This could be done even if you don’t know the old pin of the device.
SureLock’s SMS Command feature allows an authorised user to communicate with the device and perform activities like changing or setting a Lock Pin. The implementation of OTP sent over configured email for authentication of SMS commands makes the whole process safe and secure.

5. Once done save the settings file and import it on the device
6. Use a phone to create OTP using the following SMS command. This OTP will be sent to the address configured in smsotpemailtoaddresses
