Meta will close its standalone Messenger website on April 16, requiring users to log in to their Facebook accounts to access messaging online. This change will primarily affect non-Facebook users, who will no longer be able to use Messenger via a web browser without creating a Facebook account. Businesses that used the standalone site will need to adjust their workflows, as they will now have to log into Facebook to access messages. This decision is part of Meta's strategy to integrate its messaging services more closely with the Facebook ecosystem.
