How to Reset the Password on a Cell Phone
Password-protecting a cell phone is the process of establishing a code that will allow the user to access the device. A password is necessary to protect your messages, contacts and media in the event that you lose your phone or if someone tries to hack into your device. Essentially, most users should reset the password on their device every few months to keep the security measure up-to-date.
Navigate to the "Options" menu.
Select "Security" followed by "Phone."
Select the option "Change Password" or "Password" followed by pressing the "Menu" button. Then select "Change Password."
Enter the old password when prompted.
Enter the new password, and then reenter the new password again, if prompted.
Press the "OK" key to submit your change.
