Authenticator problems

Hi

I have an issue with my security option on my main account, probably during moving from one place to live to another my physical authenticator probably has been lost.
The only way for me to completely log in to my main account is only by using a code that that device would have been providing, the problem is that i don’t have the device anymore and i’m stuck looking at my own way of security.

The question is, how do i remove the authenticator temporarily in order to log in to my account so that i can remove it completely while being in my account? The support site keeps me in a loop aswell and won’t let me continue on my account.

Any advice and help would be appreciated!!

Thanks in advance
