2 factor code

Here is my predicament: long ago my wife and I started a TELUS account using her e-mail and a password. This was fine until TELUS started using the '2 factor' login that sends a number code to your account e-mail. So now even knowing her e-mail and the account password I can't login into our account from my own computer because of course the 2nd. verification code is sent to her e-mail.

I checked the security setting in 'my profile' and there was an orange triangle along with "2-factor authentication Disabled" so why is it still sending the 2 factor code? If that's the case how do I get my own e-mail added to our account?
