My name is Juventas Vijeikis I’m experienced Infrastructure Solutions Architect. Recently I had a problem to find a cheap multifactor authentication solution for Microsoft ADFS servers. I didn’t want to use user certificate option which comes for free with Microsoft ADFS as it is very expensive option to maintain. Most of the solutions which offer one-time password authentication requires monthly payments. For those who do not want to enrol into monthly subscription and want to have a free working solution out of the box, you can use one of “SecureMFA provider” modules which are available to download for free. It provides multi-factor authentication (MFA) using a Time-Based One-Time Password (TOTP) Algorithm which is based on RFC6238. This algorithm is used by Microsoft verification, Google Authentication, Symantec VIP and some other providers so you will be able to use those apps to authenticate when using “SecureMFA OTP provider” as your ADFS MFA solution.
