Synchronization of users between a CATV system and a disparate video distribution system is provided. A network account identifier tied to a household subscriber account may be linked to a plurality of users in the household. A strong authentication may only be required once (or at infrequent intervals) to initially validate credentials and authorize a requesting device. Subsequently, the device may be configured to retrieve accounts for all users in the household. Because the device is now known to the service provider, easy user-switching rules may be applied. Each user in a household may get his own personalized recommendations, use his own preferences, or tie to other individualized service personas. Any changes or updates in personalized information for a video user may be synchronized back to the originating system such that the next time the particular video user uses a CATV system device, any changes/updates may be reflected.
