Keep safe by using unusual passwords. Use a combination of letters, lowercase, uppercase, symbols and numbers. Don't use any part of your name or email address and don't use your birth date either because that's easy for people who know you to guess. Don't let anyone see you signing in and if they do, change the password as soon as you can.
Things to remember:
Some stores and other locations look for devices with WiFi or Bluetooth turned on to track your movements while you are within range. Turn off WiFi and Bluetooth when not in use, and limit your use of free public wireless networks, which stores and locations can use to track what you do online.
If you are using a public computer such as one in a library, computer shop, or even a shared family computer, be sure to sign out of any web service you are using before leaving the computer so that you can protect your privacy.
