Security Feature Overview

Security options

Using passwords

You can set a password to help protect your BlackBerry® device from unauthorized use.
You can also use the password keeper to store all of the passwords that you use to access applications and web sites on your BlackBerry device.
You need to remember only the password keeper password to retrieve all of your stored passwords.

Encrypting your BlackBerry device data

When you set up encryption of your BlackBerry® device data using the content protection feature, your BlackBerry device is designed to be
protected against users with malicious intent who could attempt to steal your data directly from the internal hardware. No one can read your
encrypted data without your device password.
In the Security Options, you can set the Content Protection Strength level. The BlackBerry device then encrypts your data (for example, messages,
contact entries, and tasks). The Content Protection Strength level optimizes either the encryption strength or the decryption time. When your
BlackBerry device decrypts a message that it received while locked, the BlackBerry device uses an encryption key. More encryption strength
means a longer decryption process.
If you set the content protection strength to Stronger, use a minimum length of 12 characters for the BlackBerry device password. If you set
the content protection strength to Strongest, use a minimum length of 21 characters. These password lengths maximize the encryption strength
that these settings are designed to provide.

Encrypting your media card data

Your BlackBerry® device is designed to encrypt media data that you store on a media card according to the Encrypt Media Files field in the
Memory section of the device options.
This encryption does not apply to files that you manually transfer to a media card (for example, from a storage device using mass storage mode).
When you store a file on a media card for the first time after you turn on mass storage mode, the BlackBerry device decrypts the encryption
key for the external memory file and uses it to automatically encrypt the stored file.
