how does an RSA token get out of sync?
In: Technology
It has a tiny, battery powered clock inside. The device is not expensive, and that limits the precision of the clock inside. The Host has access to extremely accurate time, so sync problems are certain to occur if you wait long enough. The RSA design has enough tolerance built into it that the design life of the battery is less than the likely time to get out of sync. Some batteries are extra good, some tokens are subject to unusual stresses, stuff can happen.
