Need help setting up the new Mobile App

The account I’m currently posting from is not the account that’s having trouble, I can’t log that one in using the new Mobile App.

Here’s the full problem.

  1. I have an authenticator attached to my main account.

  2. I have all the necessary information to log in and set up the 2FA that’s built into the new Mobile App. This means I have the email, password, Serial and Restore codes from the authenticator, in times past this was all I needed.

  3. I’m missing the UX flow in the mobile app, it seems to be getting stuck asking me to log in. However, until I can enter the serial and restore codes to set up the 2FA, I block when it asks me to either confirm the 4 character code, or enter the 8 digit code.

  4. I do not have the phone I was using previously, so I can’t do a migration, nor can I receive an SMS on that phone. It’s long gone: I’ve moved in the years since I last played and now have a new phone number.

So my question is this. What exactly do I do with the new Mobile App to be able to enter the serial and restore codes to set up 2FA? I can’t remove the authenticator using the web flow, because guess what. I have the option of entering a code (impossible) or receiving an SMS (also impossible). The web flow to remove an authenticator does not provide the option to receive an e-mail to confirm my identity.

As a side note, if you do your homework, there’s a growing movement that is trying to deprecate use of SMS for authentication, because it’s no longer considered secure. Search for “Is SMS 2FA secure” on any respectable search engine, and you’ll get plenty of links outlining the problems with it.
