I had to reinstall the Battle Net app on my phone.
Now, when I try to log in to the app, it asks me to tap the authenticator to approve log in, but I can’t because I’m trying to log in to the authenticator app.
I have all the restore codes, but when I try to use those, I get an error message saying ‘Oops Something Went Wrong.’
Please help.
Hey Sybilla,
Our team can help you if you have an issue with your Authenticator. You can contact us by creating a ticket to have the Authenticator removed, it’s quick. 
Once removed, you should be able to log and add the new Authenticator.
tysm it’s doing my head in. It’s like a deleted scene from ‘Brazil’. A search of the internet shows I’m not the only one. Can I give feedback and ask that someone looks into this or that Blizz make a return to having a physical authenticator alternative?
Hi Yryadorne,
Apologies for jumping into someone else’s thread, but I’m experiencing exactly the same issue.
I already opened ticket EU106433237 on Wednesday morning and have unfortunately still not received a response. I’m completely locked out of my Battle.net account due to the Authenticator/old phone number issue.
As you mentioned that this can normally be resolved quickly by removing the Authenticator, would you perhaps be able to check whether my ticket is in the correct queue or help get it looked at?
I would really appreciate any help.
Thank you.
Looks like you received a response recently Pompart. Please do check your emails, if you haven’t already. 
Thank you for your patience!
