Difficulty: Moderately Easy
Things You’ll Need:
Step1
Choose an uncommon password for your Blackberry. Choose a sequence of letters and numbers that you can remember, but not something that is obvious like your birthday or address.
Step2
The Blackberry handheld is programmed to reject passwords that are weak, like identical characters or those that are composed of natural sequences. For example, avoid combinations like "56789" or "111111."
Step3
Access the Blackberry main menu and select the "Options" menu. Press "Menu Security" and choose the "Enable" function.
Step4
Type your password and confirm it. To unlock the phone, type the password into the field when the Blackberry handheld is active.
Step5
For added security, try the "Security Timeout" feature, which automatically locks the Blackberry if it has been inactive for a while.
