A lot of Authentication as a Service platforms do a good job right up until the moment a token lands in a browser cookie. After that, you're on your own. If a malicious user manages to steal that cookie and replay it in another browser, they may be able to take over the original user's session. That is session hijacking.
The risk is easy to overlook because the login itself may have been secure. The weak point is what happens afterward. Once a token is stored on the client side, the session becomes something that can be copied, reused and abused if it falls into the wrong hands.
CentralAuth is built to close that gap.
Instead of assuming a session stays trustworthy forever, CentralAuth regularly checks whether the token still belongs to the user who started the session. In practice, that means verifying the integrity of the token and confirming that the current user still matches the original session owner. If something looks off, the session can no longer be treated as valid in the same way.
Of course, that extra protection does require a request to the CentralAuth server. But that request is designed to be as light and fast as possible, because strong security should not come with a sluggish user experience.
That is where the global infrastructure matters. CentralAuth runs multiple servers around the world, and GeoDNS always routes the request to the nearest one. The result: the shortest possible path, the lowest practical latency and a security model that does not force you to choose between safety and speed.
That balance is the point. Session hijacking is a real risk, and pretending otherwise does not make it go away. CentralAuth handles it by checking sessions continuously, staying close to the user and keeping the overhead as small as possible.
Security should not stop at login. It should stay with the session all the way through.
