Nothing is more distressing than losing your phone or thinking it has been stolen. For peace of mind, as soon as you set up your new phone, take a moment and lock it down by configuring the lock screen. Most phones during the initial set up prompt you through a process to lock down your phone, either via a PIN, pattern, password, fingerprint and/or facial recognition. My phone, I have set up to use a combination of these, with the fingerprint recognition I feel is the most powerful. My phone also allowed me to pick a 6-digit PIN, which I feel really makes it tougher to overcome.
If by chance you skipped over the process to secure your phone when you initially set it up or you desire to modify the current settings, you can do this by heading to the system settings. The system settings on most phones can be accessed via an app icon (labeled “system settings or settings”) or by pulling down from the top of the screen and tapping on a “cogged gear icon”. From the system settings, you are looking for the Security Menu. The menus and options may slightly vary from phone to phone but look for anything that is related to “security” and once there you should see various options to lock down your phone.
Just do it for peace of mind… These phones are computers in our pockets and contain a mother load of personal information.
