# Considerations When Using System Mode

System Mode is a S-Docs feature for document generation, primarily designed for unauthenticated or logged in guest users to generate documents with S-Docs in Experience Cloud contexts.

***

### 👤 **Who It's For**

* ✅ Guest users (unauthenticated)
* ⚠️ *Limited* support for authenticated **Experience Cloud** users
* 🚫 *Not* a replacement for **Run-As-User** functionality

***

### **Compatibility**

**✅ Compatible with:**

* Document Generation
* Email sending
* Best suited for **Salesforce Sites** serving **guest users**

**🚫 Not Compatible / limitations:**

* E-signature functionality (e.g., E-sign SDK)
* Batch processes
* Integration user types
* Not recommended for portals, communities that have authenticated users
