Processes, systems, and devices create personalize content for users. A user device associated with a user account is authenticated to a system supporting content replacement. A replaceable segment is identified in the content, and replacement content is selected by comparing metadata associated with the user account to metadata associated with potential replacement content. The replaceable segment in the content is replaced with the selected replacement content to generate personalized content for the user account, and the personalized content including the selected replacement content is transmitted to the user device. The content may be received from a content delivery network and may include a cue that indicates content is replaceable. The user device may be authenticated in response to a request from the user device to join a virtual meeting. The user device may send the request to join the virtual meeting in response to a unique link.
