What are the different authentication modes supported for SMTP configurations?

In Saviynt EIC,SMTP configurationis used to enable email notifications for workflows such as access requests, certifications, alerts, and system communications. To securely connect with mail servers, Saviynt supports multiple authentication mechanisms. The valid authentication modes areNTLM, OAuth, and Basic, making OptionsA, B, and Dcorrect.

Basic Authentication (Option D)is the traditional method where a username and password are used to authenticate with the SMTP server. While widely supported, it is less secure compared to modern methods and is being phased out in many environments.

NTLM (Option A)is commonly used in Microsoft-based environments (e.g., Exchange servers) and provides integrated authentication using Windows credentials, offering better security than basic authentication.

OAuth (Option B)is a modern and more secure authentication mechanism that uses token-based authorization instead of storing credentials. It is commonly used with cloud-based email services such as Microsoft 365 or Google Workspace.

OptionCis incorrect because Saviynt explicitly supports multiple authentication modes.

Thus, NTLM, OAuth, and Basic are the supported SMTP authentication modes in Saviynt.
