About users
The users feature lets you share your device with others while keeping your personal or work information private. For
example, users that you add to your device can't access your info, such as your email, contacts, pictures, apps, and more.
By default, your device is set up with a device owner and a guest. You can also add more user profiles to your device.
To improve privacy between users, each user should set up a screen lock. A screen lock prevents another user from
accessing information in a different user profile.
