# Protecting Sensitive Information

> Protect sensitive data logged at Verbose level in Studio and Orchestrator by marking activities as Private to exclude variable and argument values.

To protect sensitive information that is logged during the execution of your automation at the Verbose level, you can choose not to log variable and argument values in both Orchestrator and Studio.

To do this, you can select the **Private** property check box from the activities that use sensitive information. You can also open the context menu of an activity in the **Designer** panel and select **Mark as Private**. To remove the marking, select **Mark as Public** from the same menu.

:::note
* This property is currently not available in cross-platform projects and for some
activities in Windows projects.
* The property only applies to default log messages. It does not apply when explicitly
logging variable and argument values via activities such as **Write Line** or **Log Message**. To learn more, see [Logging Levels.](https://docs.uipath.com/studio/standalone/2026.10/user-guide/logging-levels#logging-levels)

This option is visible in the **DisplayName** of the activity:

This can also be achieved by using in the title of an activity, the reserved words from the `excludedData` parameter in the `project.json` file from a given project (`%HOMEPATH%\Documents\UiPath\[PROJECT NAME]`).

By default, only two words are reserved: "private" and “password.”

However, you can easily add custom reserved words, under the default ones, in between quotation marks. Please note that wildcards (*?) are supported.

In the example below, all the activities that have **password** in the name do not send logs to Orchestrator.
