+Currently, when you deploy in BigAnimal's cloud account, you can use AWS or Google Cloud as your cloud provider. If you want to use your cloud account's Identity and Access Management (IAM) service for database authentication, you must deploy clusters in your own cloud account. If you deploy using BigAnimal's cloud account, the underlying cloud provider is hidden, so you can't manage IAM access.

 ### Logging in to Postgres using IAM credentials
 
-If IAM integration is configured for your cluster, you can log in to Postgres using your AWS Amazon Resource Name (ARN) and access key. Using this ARN + access key combination allows you to connect to your Postgres database using your AWS IAM standard credentials.
+If IAM integration is configured for your cluster, you can log in to Postgres using your cloud credentials. Alternatively, you can use your token instead of your password. Logging in either way allows you to connect to your Postgres database using your cloud account's IAM standard credentials. 
+
+For either method, you must first authenticate to your cloud service provider IAM to get your password or token.
 
 !!! Note 
     You can continue to log in using your Postgres username and password. However, doing so doesn’t provide IAM authentication even if this feature is configured.
