in this section once you set a screen lock.
Set up SIM card lock Opens a screen where you can configure the light to require
entering the SIM PIN to use the light, and where you can change the SIM PIN.
Visible passwords Check to briefly show each character of passwords as you enter
them, so that you can see what you enter.
Select device administrators Opens a screen with a list of the applications you have
authorized to be device administrators for your light. This is typically an email, calendar,
or other enterprise application that you granted this authority to, when you added an
account hosted by an enterprise service that requires the ability to implement security
policies on the devices that connect to it. Touch an application in this list to disable its
authority to be a device administrator; if you do, the account you added will typically
lose some functionality in its applications, such as the ability to sync new email or
calendar events to your light, until you restore the application's authority as a device
administrator. Applications whose device administration authority you disable in this
way, but that have accounts that require them to be a device administrators, typically
notify you how to restore their authority when you try to use them, unless you delete
those accounts.
Use secure credentials Check to allow applications to access your light's encrypted
store of secure certificates and related passwords and other credentials. You use
credential storage to establish some kinds of VPN and Wi-Fi connections, as described
in "Connecting to networks and devices". If you have not set a password for the
credential storage, this setting is dimmed.
