2 Set Passphrase for
Secure Storage
The secure storage subsystem
contains your encrypted SMS
messages, your secure contacts,
and your secure notes.
After booting up, the phone
will ask you to set the pass-
phrase for the secure storage
container.
The strength of protection of
the secure storage container
depends entirely on how diffi
cult it is to guess your pass
phrase.
A passphrase consisting of at
least 16 characters, consisting
of a mix of letters, numbers and
punctuation characters, is rec-
ommended. For instance, you
could use the initial letters from
the words of a poem
or song text which you
remember well and
replace some of the let-
ters with numbers.
Avoid words that can be
found in a dictionary.
You can later change
the passphrase and
configure the automatic
timeout for locking the
secure storage con-
tainer in the settings.
Note: If you forget
your passphrase,
there is no way to
retrieve your data.
The encryption system
contains no backdoor
or master key. So
make sure not to for-
get the passphrase.
