Thank you for your response @Vero Rivas 
But, I don't know what phone number to use and I never activated Two Factor Authentication Code
How did this happen?
So, I can't access it from the browser
currently only via the trello mobile app currently logged in
And in the trello mobile app there is no way to disable Two Factor Authentication
