A SWA integration provides single sign-on for apps that don't support proprietary federated sign-on methods; it works with any web-based app. If your SWA app integration is successful, the following happens when end-users click the app chiclet:
The username and password fields are populated. Users are signed in to the app automatically.
A SAML integration provides Federated Authentication standards that allow end users one-click access to the app. SAML (Security Assertion Markup Language) is an XML-based standard for exchanging authentication and authorization data between an identity provider (IdP) such as Okta, and a service provider (SP). If the Zoho Application supports SAML, I would encourage you to use it as the Authentication Protocol over SWA. When SAML is enabled Okta will be the Authentication provider for the application,also, this Authentication Protocol will give you more control over your users Authentication behavior.
I've looked at those links, and they mostly seem to be about how to
configure SAML; right now, I'm mostly concerned with *if* I need/want to
configure SAML. From what I can see, the Zoho CRM app offers one click
access to Zoho CRM from the Okta dashboard. If I configure SAML, what
other benefit would my Zoho CRM users have, besides the one click access?
