The subset of interactive elements is displayed.

Abstract: In one embodiment, a method includes providing for presentation to a user a number of content objects. At least one of the presented content objects is socially relevant to the user. wherein at least one of presented content objects is socially irrelevant to the user. The presented content objects are socially relevant or socially irrelevant to the user based on whether in a social graph a node corresponding to the user is connected by an edge to a node associated with the content object. The edge represents a social relationship between the content object and the user. The method also includes receiving an input indicating a selection of a number of the presented content objects by the user; and authenticating the user based on a determination of whether the selected content objects are socially irrelevant to the user.

Abstract: In one embodiment, user information for a user of a social-networking system is retrieved. Device information is determined for a device associated with the user. Based on the device information or the user information, content associated with the user is retrieved. Using the retrieved content, a content board is composed for use in a cover feed displayed on the device The content board may comprise a background image. Finally, the content board is sent to the device. In one embodiment, updated information for content associated with the user is retrieved. The updated information may be associated with content that was included in a previously-provided content board. Using the updated information, an update to the previously-provided content boards is composed. Finally, the updates may be sent to the previously-provided content boards to the device.

Abstract: In one embodiment, a method includes accessing geolocation data indicating a current geolocation of a client device of a user; identifying one or more categories of interest to the user based at least in part on social information of the user; identifying one or more objects based at least in part on the current geolocation; and determining one or more recommendations for the user based at least in part on a calculated interest value of each identified object. The calculated interest value is based at least in part on the identified categories of interest to the user. The method also includes providing the recommendations for transmission to the client device. The recommendations include one or more of the identified objects.

Abstract: In one embodiment, a method includes accessing geolocation data indicating a first geolocation of a mobile computing device of a user of a social-networking system. The social-networking system including a graph that includes a number of nodes and edges connecting the nodes. A first node in the graph corresponds to the user. The method also includes identifying one or more second nodes in the graph connected to the first node. Each of the second nodes being associated with a second geolocation. Each of the second nodes being connected to the first node within a pre-determined threshold number of degrees of separation with at least one edge corresponding to the activity socially relevant to the user. Each edge in the graph represents a single degree of separation within the graph. The identifying being based on a determination that the second geolocation is within a pre-determined threshold distance of the first geolocation.

Abstract: In one embodiment, a method includes accessing one or more short-message service (SMS) messages received at the first mobile device from a server of a verification authority; automatically and without manual user input, processing by the application data in the SMS messages to detect a particular bit sequence; and automatically and without manual user input, transmitting the information of the first user to the verification authority from the first mobile device in response to detecting the particular bit sequence.

Abstract: In one embodiment, a method includes identifying an application installed on a client device of a first user, and one or more second users of a social-networking system that are connected to the first user within the social-networking system. Data associated with the one or more second users may be determined. The data may indicate: a number of the one or more second users who have installed the identified application, or a number of uses of the identified application by the one or more second users over a pre-determined period of time. The data, which may be configured to be displayed on the client device with an interactive element associated with the application, may be sent to the client device of the first user.

Abstract: In one embodiment, a method includes displaying one of a number of graphical user interfaces (GUIs) of one or more applications as a card on top of a card stack. One or more of the cards in the card stack corresponds to a GUI of a home screen of the computing device. Each of one or more of the cards in the card stack corresponds to one of the GUIs of an application. The application controls presentation of their GUIs as cards in the card stack. The method also includes receiving user input to display another one of the GUIs as the card on top of the card stack; and, in response to the user input, displaying the other one of the GUIs as the card on top of the card stack.
