2FA is not an option but a requisite so this is how you can set up two-factor authentication on your exchange accounts to add another level of security to your login process. It goes without saying that it would be foolish to not use such a feature in today’s uncertain world of cybercrime. Always remember, at any point in time, your security is in your own hands and you will have only yourself to blame if anything goes wrong!
