Lock a Device
The Lock action allows users to remotely lock a device from the console. This is useful when a device is lost, unattended, or needs to be temporarily restricted from use.
🔒 Locking a device is similar to the device’s screen locking when the timeout expires.
What happens when you lock a device?​
When the Lock command is sent:
- The device screen is immediately locked (if the device is online)
- The user must unlock the device using their PIN, pattern, or password
- In a Work Profile environment:
- Normally, only the work profile is locked
- Exception: On organization-owned devices running Android 8, 9, or 10, the entire device will be locked
This prevents unauthorized access while keeping the device enrolled and managed.
How to lock a device​
- Log in to the mambo EMM console
- Navigate to Management > Devices
- Find the device you want to lock
- Click the Actions (⋯) menu for the device
- Select Lock
A confirmation popup will appear.
Configure Lock Command Expiry (Optional)​
By default, the lock command expires after 10 minutes if the device is offline.
You can manually change this before sending the command.
- Enable Set custom expiry
- Enter a value (for example:
1) - Select a unit from the dropdown:
- Seconds
- Minutes
- Hours
- Click Lock to send the command
If the device does not receive the command before the expiry time, the request is automatically cancelled.
