So some time ago, I was given a free physical authenticator as part of a trial program of some sort, of which I dont really remember the specifics as this occurred in early Cataclysm.
Anyway, consider this was a solid ten years ago, my concern is that the battery life on these things is only rated for seven years. Now, I’ve tried the mobile authenticator and I prefer the physical one. This issue here is that Blizzard has long since stop selling the physical authenticators on the store. So I’m on a countdown here with an unknown amount of time remaining.
HOWEVER! The authenticator itself is a rather common model. Its a Vasco Digipass Go 6. These sell new on ebay for a few bucks each. They are not branded with Blizzard in anyway, but they do have serials on the back, same as the Blizzard ones.
Would it be possible to buy a generic unbranded ones to continue to use a physical authenticator when the rapidly approaching end of my current authenticator lifespan is reached?
