<p>In an enterprise work environment, an Android device can now be

configured with separate profiles for both work and personal use.</p>

<p>To enable bring-your-own-device for enterprise environments, a new

<a href="{@docRoot}about/versions/android-5.0.html#Enterprise">managed provisioning process</a>

creates a secure work profile on the device. In the launcher, apps are shown with a Work badge to

indicate that the app and its data are administered inside of the work profile by an IT

administrator.</p>

<p>Employers can issue devices with a <em>device owner</em> app

installed that can create and remove secondary profiles and configure

global device settings. Alternatively, employees can bring their own

device and the employer can add a secure work profile to the device.</p>

<p>Notifications for both the personal and work profile are visible in a unified view. The data

for each profile is always kept separate and secure from each other, including when the same

app is used by both profiles.</p>

<p>Notifications and apps for both the personal and work profile are

visible in a unified view, and apps for work are badged so users can

identify them easily. The data for each profile is always kept separate

and secure from each other, including when the same app is used by both

profiles.</p>

<p>For company-owned devices, IT administrators can start with a new device and configure it with a

<a href="{@docRoot}about/versions/android-5.0.html#DeviceOwner">device owner</a>. Employers can

issue these devices with a device owner app already installed that

can configure global device settings.</p>
