A technology company that routes millions of SMS text messages across the world has secured an exposed database that was spilling one-time security codes that may have granted users’ access to their Facebook, Google and TikTok accounts.

The Asian technology and internet company YX International manufactures cellular networking equipment and provides SMS text message routing services. SMS routing helps to get time-critical text messages to their proper destination across various regional cell networks and providers, such as a user receiving an SMS security code or link for logging in to online services.
