Is it possible to have multiple SSO configured to a single web app?

Question

I was wondering if I can configure my web application to authenticate in different identity providers such as Azure, AWS, Okta, etc.? For example, I have an application and I want to login using my Azure Account. And with that same application, I also want to login using my AWS account. Is that scenario possible? If yes, how will I implement it?

Answer 1

This isn't offered with every identity provider, but it does look like Azure has a guide for setting up Azure Active Directory single sign-on (SSO) integration with AWS Single-Account Access. This allows your users to be automatically signed-in to AWS Single-Account Access with their Azure AD accounts.

AWS appears to have a corresponding guide.

Okta appears to have a guide for making Azure AD an identity provider but there is no corresponding documentation from the Azure side.
