SlickLogin was an Israeli start-up company that developed sound-based password alternatives. The company's goal was to enable end users to log in easily to password-protected websites by using a uniquely generated sound.
The company was founded by Or Zelig, who served as the firm's CEO, Eran Galili, CTO, and Ori Kabeli, VP of R&D. They were recent graduates of the IDF's elite cyber-security unit and spent over six years working on information security projects.
SlickLogin used various protocols to start verifying your phone's position: WiFi, Bluetooth, NFC, visual markers like QR codes, and of course, GPS. Their self-dubbed "secret sauce", though, was their use of uniquely generated sounds intentionally made inaudible to the human ear. The user's computer played the sound through speakers, while a mobile app used the device's built-in microphone to pick up the audio, analyze it, and send the signal to the site's server for authentication.
