If you touch PIN or Password, you’re prompted to set a
numeric PIN or a password you must enter to unlock your
screen.
The next time you turn on your phone or wake up the screen, you
must draw your unlock pattern or enter your PIN or password to
unlock it.
IMPORTANT: Screen lock options are listed in the approximate
order of the strength of their security, starting with None and
Long press, which provide no security. A pattern provides
minimal security, although it can be more convenient than the
stronger options.
Protecting Your Phone With Encryption
You can encrypt all the data on your phone: Google Accounts,
application data, music and other media, downloaded information,
and so on. If you do, you must enter a numeric PIN or password
each time you power on your phone.
WARNING! Encryption is irreversible. The only way to revert to
an unencrypted phone is to perform a factory data reset, which
erases all your data.
Encryption provides additional protection in case your phone is
stolen, and may be required or recommended in some
organizations. Consult your system administrator before turning it
on. In many cases the PIN or password you set for encryption is
controlled by the system administrator.
Before turning on encryption, prepare as follows:
1. Set a lock screen PIN or password.
