Battle.net Authenticator?

Can anyone tell me if this is a problem? I’m looking at the reviews of others and it seems to have VERY poor expectations and a lot of serious bugs.
Does anyone have any positive experiences with the app or is it just not worth the worry to use it?
Thank you for any feedback or advice.

I use a physical authenticator I bought off Amazon a couple years ago (still available) and it works great.

I will admit though the game has not asked me to use it in the past year or so.

Before it I got hacked a couple of times. I’ve had the Authenticator for many years and never again did I have that problem :slightly_smiling_face:

I just use WinBMA when I want to play untethered by a cell phone.
