2FA -not able to login

Hii ,i have enabled 2FA in my account but recently i have changed my mobile device and not able to get OTP for authentication.I dont have my recovery codes with me and i have not added ssh keys in my account so i am not able to fetch through using a terminal.I was curious whether we can turn off 2FA for my account.
