Does anyone know how to disable SMS 2 Factor Authentication?

I have google authenticator enabled on my account, but T-mobile still allows SMS and secret questions as 2FA methods as well.  This is not secure, especially after this week’s data theft.  What’s the point of enabling google authenticator if it can be bypassed by selecting the DEFAULT of SMS 2FA?

I just spoke with an Agent about this yesterday.  Not a hint of a clue.  He thought this was an IOS thing, and wanted to forward me to an Apple specialist.  Very nice person, and not his fault at all, as leadership and training comes from above.  It’s quite clear that T-Mobile is not offering the option to disable SMS authentication.  

I too would like a way to disable SMS based 2FA - what is the point of using an authenticator app if the option to receive a code via Text is still enabled. Give us an option to disable SMS based 2FA @TMOBILE!

I am looking for the exact same information.  The SMS pin message is a huge liability and I cannot find a way to disable it.

You said it precisely.  Come on T-Mobile, it’s bad enough that we have to endure data breaches repeatedly, but the inability to remove an account feature that is a huge liability to security??  It isn’t like we don’t have choices out there for alternate carriers, you know.
