+# .NET CLI `--interactive` defaults to `true` in user scenarios
+
+The `--interactive` flag for the .NET CLI now defaults to `true` in user-centric scenarios. The behavior remains unchanged for CI/CD environments.
+
+## Version introduced
+
+.NET 10 Preview 3
+
+## Previous behavior
+
+The `--interactive` flag always defaulted to `false` unless explicitly specified by the user.
+
+```bash
+dotnet restore --interactive
+# Required explicitly to enable interactivity
+```
+
+## New behavior
+
+The `--interactive` flag defaults to `true` in user-centric scenarios, such as when commands are run directly by a user. In CI/CD environments or when the process output stream is redirected, the flag defaults to `false`.
+
+```bash
+dotnet restore
+# Interactivity is enabled by default in user-centric scenarios
+```
+
+## Type of breaking change
+
+This is a [behavioral change](../../categories.md#behavioral-change).
+
+## Reason for change
+
+This change improves the user experience by:
+
+- Simplifying NuGet authentication, addressing a common pain point.
+- Providing a unified signal for enabling future CLI interactivity features.
+
+## Recommended action
+
+No action is required for most users. To explicitly disable interactivity, pass the `--interactive false` flag:
+
+```bash
+dotnet restore --interactive false
+```
+
+## Affected APIs
+
+None.
