In the rapidly evolving digital media landscape, users face the inconvenience of managing multiple accounts across various news and entertainment portals, leading to fragmented experiences and reduced engagement. KGMediaID, overseeing 72 news portal websites, identified that this account fragmentation deterred users from fully exploring available content, such as articles, entertainment features, and interactive systems. Additionally, the lack of unified access hindered the ability to offer premium content—like series, stand-up videos, and games with scoring and leaderboards—while generic engagement tools (e.g., bookmarking, liking, and commenting) were inconsistently implemented or absent. The challenge was to create a seamless, secure, and engaging user experience across all portals, encouraging retention, interaction, and monetization through a single account system. Users also expressed concerns about security and preferred familiar login methods, necessitating a system that could integrate trusted third-party authentication providers.
