This TextKey PHP library allows you to use SOAP API calls server-side from a PHP backend. TextKey is an omni-factor authentication API that uses seven-factors of authentication to provide security for devices ranging from mobile to electronic door locks. TextKey works through using SMS service, unique code, cellular number, UDID, a single use URL, and an optional pin. TextKey uses Rest with a JSON response and SOAP. TextKey is free for ten users, and available for a monthly charge per user thereafter.
LandMark White, Australia's largest independent property valuation and property consultancy firm, is reported to have exposed the home loan details of up to 100,000 customers in a recent security breach that the company is blaming on an insecure API.
