You will want to create a generic Gmail account to sign up for WAVV. This way if now or in the future you are having someone dial for you, you can have the 2 factor authentication email forwarded to the callers email. You are not giving them access to this email, you are only forwarding the emails for 2FA. The only thing you will use this email account for is to sign up for WAVV and have the 2 factor authentication emails forwarded to the person using WAVV.
