Tasker: Disable Pin Lock Near Home

Introduction

If you’re away from home it’s very important to have a pin or password lock on your phone, just in case you misplace it or it is stolen.  Typically the modern mobile phone is a gateway to a multitude of private services and data, such as personal photos and videos, cloud based data, social media, shopping accounts and even bank account access.  A password lock will not necessarily prevent the determined person from gaining access to your phone, but it will at least prevent instantaneous, unchallenged, access to compromising services.  The idea is that you would shutdown access to these services at the earliest possible time after your phone has been discovered missing, and hopefully before access to the mobile phone is gained.
