Users appreciate the concept of this WordPress plugin for membership sites, which aims to prevent account sharing by logging out the first user when another session is detected. It helps ensure only one person per account, making it beneficial for membership-based websites to control access. However, users highlight several drawbacks, including that it doesn't effectively restrict parallel login access as expected, especially for certain content pages. Some users also mention that it doesn't work with specific WordPress versions, like 4.8. Additionally, the plugin description can be misleading. Despite its concept, users found simpler code solutions that achieve the same goal without needing a plugin.
