This uses Google's Inactive Account Manager (https://www.google.com/settings/account/inactive) and IFTTT to make a digital "Dead Man's Switch". Requires setup on Google Inactive Account Manager. Just add your gmail email to the Inactive Account Manager, along with a secret subject. Then use the same subject for the gmail trigger below. I recommend replacing the #'s in the trigger below to random letters and/or numbers. This helps keep everything more secure. More details at: http://goo.gl/7zzt1t
