Yesterday I got an androi phone and decided to get the mobile authenticator app. After installing it i realized that it is actually literally 100x better than the key-chain one u can buy from blizz store.
A regular authenticator has 6 digits giving you 1:1,000,000 chance to guess the combination which is reset every 30sec. And for a Price of $6.50 its a good deal to protect your account. However, and this is a big one, mobile authenticator have 8 digites giving you 1:100,000.000 change to guess the number which is reset ever 30sec and its...free. This defeats the purpose of ever having to buy the regular authenticator. I mean why would I pay 6.50 for a product when i can get a better one for free? I mean yes if you dont have a iPhone/Andoird/Blackberry i guess u're stuck with the keychain one but stil smartphones are more common and becmon more and more widespread. I mean why make an app thats free better than the keychain one which is 6.50 and is technically less secure. I would understand if it was otherway around and the 6.50 would justify two extra digits of hack-proofing. What are your thoughts?
