In some implementations, a system may receive, from a user device, a user-side request associated with establishing an application session, wherein the user-side request includes an optical code. The system may receive, from an agent device, an agent-side request associated with the agent device joining the application session, wherein the agent-side request includes authentication information that indicates that the agent device scanned the optical code from an output component of the user device. The system may send, to the user device, a notification to permit the user device to join the application session. The system may activate the application session to permit the user device and the agent device to communicate via the application session.

A document editing system using a third party application having an embedded document editing module is disclosed. The system includes a client-side document editing engine that accepts requests to edit a document from and displays at least a portion of the document to a user of the client-side system. The system includes a first server-side application engine that processes the requests to edit the document. The system can include a second server-side data storage engine that stores the document in a remote storage location.

A method for sharing a reason cause for a mission critical communication (MCX) communication over pre-established session in an MCC network is provided. The method includes transmitting, to the server, a call initiation request to initiate a call, wherein the call initiation request includes first information on a session type and second information on a resource list, receiving, from the server, a mission critical pre-established session control (MCPC) connect message including a security message, determining whether an authentication for the security message is successful, and transmitting, to the server, a first MCPC acknowledgement message including a reason cause field to inform a reason for terminating the call in response to determining that the authentication for the security message is not successful.

Techniques are disclosed for managing media playback among an ad hoc group of playback devices. Such techniques may involve building a session among the playback devices in which playback devices communicate information regarding their playback capabilities. Based on the playback capabilities of the devices, playback mode may be derived for the session. Playback operations may be synchronized among the devices that are members of the session, in which devices receive identification of asset(s) to be rendered pursuant to the playback operation and timing information of playback of the asset. The devices may stream the playback assets directly from media sources when they are capable of doing so. In this manner, communication resources are conserved.

A computer-implemented method includes identifying behavioral characteristics of a user related to operation of a computing device prior to an online account session. The method includes comparing the behavioral characteristics to a behavioral profile previously developed based on prior behavioral characteristics of the user, and determining an appropriate mark difficulty level based on a variation between the behavioral characteristics and the behavioral profile. The method includes selecting, from a plurality of prompts stored in a prompt database, a prompt that comprises instructions to draw a mark having the appropriate mark difficulty level, where other prompts of the plurality of prompts comprise instructions to draw other marks different from the mark, and providing the prompt to the user as part of a logon process for the online account session.
