# ListUserPoolClientSecrets


Lists all client secrets associated with a user pool app client. Returns metadata about the secrets. The response does not include pagination tokens as there are only 2 secrets at any given time and we return both with every ListUserPoolClientSecrets call. For security reasons, the response never reveals the actual secret value in ClientSecretValue.
