# Devices

With the built-in Flow Basic Mobile Security Management all connected mobile devices can be overviewed and managed directly in the Studio or via a workflow.\
 If *Device Management* is enabled for the environment all new devices that tries to log in to the environment need to be approved before the user actually can log in to Flow via a mobile client. In the same way existing devices can be blocked if, for example, a device is lost or replaced.

Devices that are unhandled will have status *New* and an administrator can either *Approve* or *Block* the device. Every time a user logs in from an approved device will the *Last User* field be updated with the latest logged in user.

Until the device is approved the client user will get the message *This device has yet to be approved by a system administrator*.

If the device is blocked the client user will get the message *This device has been blocked by a system administrator*.

#### System event <a href="#system-event" id="system-event"></a>

With the system event *Device Status Changed* it is possible to automate some of the device management and for example alert administrators with an email if a new device is connected.

> Use the Flow environment connector and the functions related to *Device management* to for example approve or block devices via a workflow.
