ICane;
Do you have a cell phone?
If so; there is an app for the security Token.

I do have a cell phone and I am aware of the software security token. I went for a physical token because I very well remember the pita that was removing a similar token from my Steam account after my old phone got stolen.

Now for the other questions:
- My provider is 1&1; I already contacted them but am still waiting for any kind of response
- I have a DSL connection and my computer is connected to the Router via cable
- I only access the game and sites like the Lodestone with one device


I use Opera as a browser of choice and I am aware it has a build in VPN. That is disabled.

There are still two things boggling my mind.

1. This security measure is only triggered on days I log in into my Square Enix account via browser. Maybe this is a coincidence.
2. Why have simple disconnects become security concerns in the recent weeks?
