Many Steam users are currently experiencing difficulties logging into the platform due to a persistent "loading user data" screen. The issue has been ongoing for several hours, and its exact cause remains unclear. While SteamDB's status page indicates normal operation, Down Detector has seen a significant increase in user-reported problems beginning around 6 am ET. Discussions on the Steam Support subreddit also corroborate these widespread login failures.
Some users have reported temporary success by closing Steam and relaunching it as an administrator, though this solution has not worked for everyone. One prevailing theory suggests a connection between the login problems and the process of purchasing or downloading games. While initially experiencing login issues myself, allowing Steam to sit on the "loading user data" screen for an extended period eventually resolved the problem, and subsequent game downloads proceeded without further incident. This suggests that patience may be a viable, albeit frustrating, temporary solution for some.
Valve has been contacted for comment regarding the ongoing login difficulties. This story will be updated as more information becomes available or when the issue is resolved.
