Abstract: In some embodiments, after authentication of a user at a trusted device, a system may store a record with user or other support information and a code in a database. When support is requested by the user device, the code provided in response to the request (e.g., as an extension to a phone number or in a header field), and a system may use the code to retrieve the record from the database. Presence of the record in the database may indicate to the communication system that the user requesting support is already authenticated.

Abstract: Systems as described herein may include website data surfacing. A data surfacing system may provide user interaction information to a machine learning model as input. Based on output from the machine learning model, the system may determine a likelihood that the user would navigate away from a website. After determining that the likelihood exceeds a threshold value and before the user navigates away from the website, the system may determine a second product in an inventory list that is similar to the first product on the website that is out of stock using a second machine learning model. Accordingly, the system may cause display of the second product in an overlay window displayed in the website using a browser extension on a user device.
