Hello Girish,
I assume that when you say "web SSO" you mean that once signed into your Google account you are able to use Single Sign-On to access SAS Viya. For this you will want to look at configuring OpenID Connect. This is covered in the documentation here: https://go.documentation.sas.com/?cdcId=calcdc&cdcVersion=3.4&docsetId=calauthmdl&docsetTarget=n1pkgyrtk8bp4zn1d0v1ln4869og.htm&locale=en#p1ubaum4cjrxu1n13tlf8ty60d4d.
Also I have some SAS Communities content on OpenID Connect here: https://communities.sas.com/t5/SAS-Communities-Library/SAS-Viya-3-2-External-OAuth-for-SAS-Logon/ta-p/372098 and here: https://communities.sas.com/t5/SAS-Communities-Library/SAS-Viya-3-4-Simplified-SAML-or-OpenID-Connect-Integration/ta-p/575811.
