Recently, I have started to receive new bank security tokens for internet login verification purposes.
Previously, I was using SMS authorization for some of the banks but it looks like the trend now is going towards more of having an unique security token for each bank.
So at this point in time now, I have the three security tokens as shown in the picture below. One from DBS, one from OCBC and one from UOB.
It can be quite a hassle to carry all these around but thankfully, some of the banks still allow for SMS verification (now) even with the token. I can’t imagine the day when I have to carry all these around with me.
The interesting thing is that all the tokens have the same size and buttons. The only thing different is the colour and how the exterior looks. I would not be surprised at all if they were all manufactured by the same vendor.
I think Gmail provides a more flexible approach. Their two-factor authentication allows you to choose either SMS or a smart phone application as the delivery method. This is much better than burdening you with an additional physical device.
