Cognito user pool OIDC federation: Add "acr_values" parameters in OIDC flow requests

Question

Hi,

I'm using Amazon Cognito, I want to federate my user pool with an external OIDC identity provider. The OIDC provider requires all OIDC flow requests must contain a parameter named "acr_values" in the request URL. 
Is there any way to custom OIDC requests in Cognito to achieve this?

Thank you!

Answer

Have you looked into using custom attributes for the user pool? You could add a custom attribute with "acr_values".

Every user pool could have up to 50 such custom attributes. Here is the documentation with more details  https://docs.aws.amazon.com/cognito/latest/developerguide/user-pool-settings-attributes.html
