# How to enable/disable lost mode on ChromeOS devices?

The **Enable Lost Mode** remote action in Hexnode UEM secures misplaced or stolen **ChromeOS** devices by locking the interface to prevent unauthorized data access until the device is recovered.

**What is Lost Mode for ChromeOS?**
-----------------------------------

**Lost Mode** is a security state that remotely locks a ChromeOS device, rendering it unusable to unauthorized parties. It serves as a critical defense mechanism against data breaches resulting from physical device loss or theft.

- **Security**: Locks the device immediately upon execution of the remote command.
- **Data Protection**: Supplements existing encryption and password policies by adding a remote-triggered access barrier.
- **Recovery**: Once the administrator confirms the device is back in authorized hands, the state can be reversed using the **Disable Lost Mode** command.
