Login to digits web portal requires 2fa code from my cell phone

Hola,

I would like to access the Digits web site at times when I do not have my cell phone in order to check my text messages.

When I try to login to the Digits web site, it asks for my T-mobile username/email, my T-mobile password, and then it wants to do 2fa via a text message to my cell phone. However, I don't have my cell phone.

I cannot find a setting on the Digits web site or my T-mobile account page to disable 2fa via text message to cell phone. When logging in to the normal T-mobile account page, it sometimes does 2fa via text message and sometimes via Google Authenticator, but I cannot figure out why it does one versus the other. However, when logging in to the Digits web site, it never tries to do 2fa via Google Authenticator; it only attempts it via text message.

Please help me either disable 2fa on Digits, force it to use Google Authenticator as 2fa, or force it to use email as 2fa.
