Data encryption
By default, data on your device, including your account information, apps, music, pictures, and other downloaded files, is
stored in a format that can be read only when your device decrypts the data. If you set up a screen lock and require that it
must be entered to turn on your device, your password, PIN, or pattern is used to generate a new encryption key to decrypt
your data.
SIM card PIN
You can set up a PIN for your SIM card, which you can use to help prevent unauthorized use of your SIM card in another
device. For example, if you lose your SIM card and someone tries to use it in another device, the SIM card can't be used
unless the PIN is entered correctly.
Network lock and unlock codes
To use a SIM card from another service provider, for example, if you’re traveling and want to use a local service provider’s
network, you can request unlock codes (MEP codes) from your current service provider. After you insert the new SIM card,
enter the unlock code.
If you exceed the number of allowed attempts to enter an unlock code, your SIM card allows emergency calls only. For
assistance, contact your service provider.
™
account and factory reset protection
The factory reset protection feature uses your Google
™
account information to help protect the data on your device. If your
device is lost or stolen, the factory reset protection feature is designed to prevent someone else from being able to set up
your device for use, even if that person tries to reset your device to its factory settings. The device must be set up using the
same Google
™
account information that was set up on the device before it was reset.
To use the factory reset protection feature, you must set up a screen lock and you must add your Google
™
account to your
device.
Set up or change a screen lock
Locking your device can help prevent your device from sending accidental messages or pocket dialing. Before you can
unlock your device and access the data on your device, you must enter your password, PIN, or pattern, or swipe the screen.
If you use your device for work, depending on the rules set up by your administrator, you might not be able to use a pattern
or swipe gesture to unlock your device.
Note:
Using a swipe gesture to unlock your screen is not a secure way to prevent others from accessing the data and
features on your device.
