Google has acquired SlickLogin, a sound-based password company. SlickLogin said that they will be joining Google to “make the Internet safer for everyone.” The terms of the deal are undisclosed.
SlickLogin verifies a user’s identity and logs them in. The identity is verified by playing a unique nearly-silent sound through computer speakers. An app on the smartphone grabs the sound, analyzes it, and sends the signal back to the website server confirming that you are who you claim you are.
SlickLogin also uses protocols to verify the phone’s position such as WiFi, Bluetooth, NFC, QR codes, and GPS.
