Square Enix Token Mobile App: Is It Reliable?

[Feyniphia]

Thanks, but I'm still curious as to why though. What's wrong with the mobile version? I have the Google Authenticator app on my phone (Which I really should set up to use again...) for my Gmail account so I'm just curious as to the reasoning not to use the mobile version of the Security Token.

Software can glitch and be rendered unusuable (It's a bitch when it happens...), can be hacked (It's very unlikely to happen, but can happen) - The physical one is near impossible to hack, usually is faster to change codes and lasts a long time (up to 10 years if you got a GOOD ONE.) In the end, the decision remains yours whether you want to change it or not. In your place, I'd keep the physical one.
