Active Directory Federation Services


Multi-factor authentication (MFA) is an extra layer of security used when logging into websites or apps in which individuals are authenticated through more than one required security and validation procedure that only you know or have access to. Acceptto offers a simple solution for adding MFA for Active Directory Federation Services (AD FS) v3.0 on Windows Server 2012 R2 and v4.0 on Windows Server 2016. With this feature, customers can use AD FS as their Identity Provider (IdP) to login to their applications and empower it with Acceptto MFA to provide a strong method of authentication.
