  • Patent number: 8520848
    Abstract: A password management service located either on a user computer or in the cloud intercepts a user's attempt to create an account on a Web site. The user enters a sequence of a physical key combination and the service assigns a particular keyboard layout for this Web site. The service generates a password by combining the key combination with the assigned keyboard layout and returns this password to the user or to the Web site. The service stores the name of the Web site in association with the designated keyboard layout. Upon a subsequent login attempt, the service again intercepts the user's typing of the same physical key combination, generates the same password by combining the key combination with the previously assigned and stored keyboard layout, and returns the generated password to the Web site for authentication. A keyboard layout for a site may be chosen by the user, may be selected by the service, or a random layout may be generated.
