JNS.org – Google has purchased its fifth Israeli company, the Tel Aviv-based start-up SlickLogin, whose technology verifies and authenticates user identity (when logging onto a website) by using an audio signal sent through a smartphone app.

SlickLogin founders Or Zelig, Eran Galili, and Ori Kabeli began developing their program in August 2013. In September, they presented it at San Francisco’s technology start-up conference TechCrunch Disrupt, and in December registered as an official company.

The three-man company—which has not yet registered a patent or recruited investors, and has no customers—joined Google’s global team operating out of Tel Aviv.

SlickLogin said Google “shares our core beliefs that logging in should be easy instead of frustrating, and authentication should be effective without getting in the way.”
