NEXUS 7 GUIDEBOOK SECURE YOUR TABLET 75
Encrypt your tablet
You can encrypt all the data on your tablet: Google Accounts, app
data, music and other media, downloaded information, and so on.
If you do, you must enter a numeric PIN or password each time
you turn on your tablet. Note that this is the same PIN or pass-
word that you use to unlock your tablet without encryption, and
cannot be set independently.
WARNING: Encryption is irreversible. The only way to revert
to an unencrypted tablet is to perform a factory data reset,
which erases all your data.
Encryption provides additional protection in case your tablet is
stolen, and may be required or recommended in some organiza-
tions. Consult your system administrator before turning it on. In
many cases the PIN or password you set for encryption is con-
trolled by the system administrator.
Before turning on encryption, prepare as follows:
1. Set a lock screen PIN or password.
2. Charge the battery.
3. Plug in your tablet.
4. Schedule an hour or more for the encryption process: you
must not interrupt it or you will lose some or all of your data.
When you’re ready to turn on encryption:
1. Touch Settings > Personal > Security > Encryption > Encrypt
tablet.
2. Read the information about encryption carefully.
