123Movies has been a popular streaming website for a long time across the globe. It was a free movie streaming site that enabled users to watch movies online without paying subscription fees. But, this streaming platform couldn't last long because the Motion Picture Association of America (MPAA) labeled the site as illegal for containing pirated content. Later, the Vietnamese authorities conducted an investigation, and the site went offline in 2018. However, users can use various clone sites to enjoy a similar experience to the original 123Movies site. The mirror sites are a good option to access 123Movies, but there are often privacy concerns associated with them. Thus, it's better to use 123Movies alternatives.
