AWS Amplify federatedSignIn for multiple SAML providers

Question

We need to support multiple identity providers on Cognito, therefore there will be multiple identity provider configuration will be set as SAML.

But I know that we need to provide the providerName as customProvider on AWS Amplify

const resp = await Auth.federatedSignIn({customProvider:'customSamlProviderName'})

how can we provide multiple providerName to Auth.federatedSignIn object? I just want to show only single login button for this.

Thanks!

Answer 1

As multiple identity provider name is not supported on

Auth.federatedSignIn({customProvider: 'providerName'})

we have decided to implement Home Realm Discovery, to fetch the relevant identity provider name by customer and dynamically set on Auth.federatedSignIn call.
