# GetIdentityCenterAuthToken
<a name="API_GetIdentityCenterAuthToken"></a>

Generates an encrypted authentication token that propagates the caller's Amazon IAM Identity Center identity to Amazon Redshift clusters. This API extracts the Amazon IAM Identity Center identity from enhanced credentials and creates a secure token that Amazon Redshift drivers can use for authentication.

The token is encrypted using Amazon Key Management Service (KMS) and can only be decrypted by the specified Amazon Redshift clusters. The token contains the caller's Amazon IAM Identity Center identity information and is valid for a limited time period.

This API is exclusively for use with Amazon IAM Identity Center enhanced credentials. If the caller is not using enhanced credentials with embedded Amazon IAM Identity Center identity, the API will return an error.
