# 5. Privacy-Based Account Access

1DEX prioritizes user privacy, offering flexible account management and permission control mechanisms:

* **Sub-Account Activation:** Allows users to create sub-accounts for asset isolation and management across different scenarios.
* **Funding Allocation:** Users can flexibly allocate funds to different accounts or purposes, improving capital efficiency.
* **Permission Control:** Fine-grained permission settings ensure users maintain full control over account operations, reducing risks of errors or unauthorized access.
