Abstract: In general, the subject matter described in this disclosure can be embodied in methods, systems, and program products. A computing device can present a messaging user interface and receive user input of a typed message through interaction with the messaging user interface. The typed message can be sent for distribution to a second user account. The computing device can receive a system-generated response to the typed message that was generated by a searching system based on content of the typed message. The system-generated response to the typed message can be presented in the messaging user interface along with an indication that the system-generated response was generated by the searching system.

Abstract: In one embodiment, a network element comprises one or more processors, and a memory module communicatively coupled to the processor. The memory module comprises logic instructions which, when executed by the processor, configure the processor to receive, via a first communication channel, a primary authentication request transmitted from a user from a first device, process the primary authentication request to determine whether the user is authorized to access one or more resources, in response to a determination that the user is authorized to access one or more resources, initiate, a secondary authentication request, and transmit the secondary authentication request from the network element to the user via a second communication channel, different from the first communication channel.
