 ## Authentication
 
-StackQL uses Azure application credentials obtained using the <CopyableCode code="az login" /> command from the Azure SDK.  For more information, see <a href="https://learn.microsoft.com/en-us/cli/azure/authenticate-azure-cli">here</a>.
+The following system environment variables are used for authentication by default:  
+
+- <CopyableCode code="CONFLUENT_CLOUD_API_KEY" /> - Confluent Cloud API key (see <a href="https://docs.confluent.io/cloud/current/security/authenticate/overview.html#api-keys">Confluent Cloud API Keys</a>)
+- <CopyableCode code="CONFLUENT_CLOUD_API_SECRET" /> - Confluent Cloud API secret (see <a href="https://docs.confluent.io/cloud/current/security/authenticate/overview.html#api-keys">Confluent Cloud API Keys</a>)
+
+These variables are sourced at runtime (from the local machine or as CI variables/secrets).  
+
+<details>
+
+<summary>Using different environment variables</summary>
+
+To use different environment variables (instead of the defaults), use the `--auth` flag of the `stackql` program.  For example:  
+
+```bash
+
+AUTH='{ "confluent": { "type": "basic", "username_var": "MY_CONFLUENT_CLOUD_API_KEY_VAR", "password_var": "MY_CONFLUENT_CLOUD_API_SECRET_VAR" }}'
+stackql shell --auth="${AUTH}"
+
+```
 
-### Authenticating using an Azure Service Principal
+or using PowerShell:  
 
-To authenticate using an Azure Service Principal, set the following environment variables: <CopyableCode code="AZURE_TENANT_ID" />, <CopyableCode code="AZURE_CLIENT_ID" /> and <CopyableCode code="AZURE_CLIENT_SECRET" />, see [__creating-an-azure-service-principal__](https://learn.microsoft.com/en-us/azure/developer/go/azure-sdk-authentication-service-principal?tabs=azure-cli#2-create-an-azure-service-principal).
+```powershell
+
+$Auth = "{ 'confluent': { 'type': 'basic', 'username_var': 'MY_CONFLUENT_CLOUD_API_KEY_VAR', 'password_var': 'MY_CONFLUENT_CLOUD_API_SECRET_VAR' }}"
+stackql.exe shell --auth=$Auth
