Authentication refers to the way users sign on. If your installation of P6 EPPM is hosted on the Oracle Cloud and configured to use Oracle Identity Cloud Service (IDCS), administrators can — and should — implement Single Sign-On (SSO) with SAML. SSO with SAML reduces the number of passwords users have to remember. It can also be used to enable multi-factor login, which is when users are asked to provide some verification in addition to their passwords, like a code that they receive via text or email.
If your P6 EPPM environment is hosted on the Oracle Cloud and provisioned in Oracle Cloud Infrastructure (OCI), it comes with IDCS.
