AWS Cognito SSO provides the capability to integrate with multiple identity providers (IdPs) for user sign-in. This allows your users to authenticate with any of the authorized identity providers of your choosing. To configure multiple identity providers, follow these steps:
- Create an AWS Cognito User Pool and configure the necessary settings, including the app client and domain.
- Choose "Federation" in the "App integration" tab of the User Pool console.
- Choose "SAML" as the federation provider and configure the provider metadata URL or upload the XML file directly.
- After the first IdP is configured, choose "Add provider" and repeat steps 3 and 4 for each additional IdP.
- Once all IdPs are configured, go to the "Attribute mapping" tab and map the user attributes from each identity provider to the corresponding user attributes in the AWS Cognito User Pool.
- Configure the AWS Cognito App Client to allow federation from the IdPs you have configured.
- Add any necessary scopes and permissions, and configure the AWS Cognito domain for user authentication.
By following these steps, you can use multiple identity providers with AWS Cognito SSO to provide your users with a seamless authentication experience.
