Clef (app)
From Wikipedia, the free encyclopedia
Clef was a San Francisco-based technology company, known for developing a mobile app that created a two-factor authentication for websites.[1][2] It allowed users to access sites with a single login password management service which stores encrypted passwords in private accounts.[3][4] It had a standard verification method that requires access to data on the mobile phone to confirm the user's identity.[5][6] The application required a Wi-Fi or mobile network, and the user could log in by scanning the computer screen with their phone.[7][8]
