Common Smartphone Security Features and How They Work
There are several security functions on the
average smartphone intended to protect your data frоm the outside world.
Devices have always had several options for users to emрloy, but as mobile
technology advances, the nυmbers of ways to unlock a smartphone оnly increase.
Gone are the days when devices has only
password, PIN, and pattern unlock options. In recent years, product makers have
begun adding various biometric security features to smartphones. These measures
allow device owners to use various body parts including fingerprints, faces,
irises, and voices to unlock their devices.
These functions can be set up in accordance
with a user’s lifestyle. Smartphone users can also set up several unlock
features for different security options on a devices. Take a look at all of the
unlock features you may find on a smartphone, how they work, and how they may
be beneficial to you as a user.
Note: While these directions are more specifically for Android smartphones,
they are easily translate to iPhones where applicable
None/Swipe
Many smartphone users commonly leave no mode
of security on their devices, by setting it to have no passcode of any kind, or by using the Swipe to Unlock setting. This method leaves no mode of protection
for a smartphone and typically isn’t recommended. If a device is lost or
stolen, other users will have direct access to your most sensitive information.
If you insist on leaving your device without a security feature set, consider having a password protected folder of some kind on your smartphone. You can keep your most important information and apps in that folder, while having easy access to your smartphone for more mundane tasks.
To set this option for your smartphone, access
Settings, Lock Screen & Security, and then screen lock type. If you have one, input your passcode or backup
PIN to proceed. Select None or Swipe among the lock screen options.
Your device will return to the previous settings page to confirm.
Password
The password security option is the same as any other security option for a website or app. You can set a series of numbers, lowercase or capital letters, and characters as your password. A password is considered a high security option, but it depends on the complexity of your password sequence.
To set this option for your smartphone, access
Settings, Lock Screen & Security, and then Password. You will see a warning that explains if you forget your
password, you will have to wipe your device and take it back to factory
settings. This means you would lose all of your data if it is not backed up
externally.
Input your password once, select continue, and
then again to confirm. If available, select the eye option to your right that
will allow you to see the password as you type it. This will ensure you’re
typing the password correctly. Select Ok.
This will take you to a notifications settings page, where you can decide
whether you want to receive notifications on your lock screen and how much
detail will be shown on lock screen notifications. Choose your preferences and select Done.
It is highly recommended that you don’t use
your smartphone password for any as a passcode for any other device, service,
website, or app.
PIN
The PIN security option is popular among
smartphone users because such codes are typically easy to remember. Users often
select numbers that are of significance to them, making them less likely to
forget. A PIN is considered a medium high security option, but it depends on
the length and complexity of your sequence.
A PIN is typically a series of numbers.
Depending on the device, your PIN can be between four and six characters long.
Many smartphones use PIN codes as a backup security option for other login
methods, so there is a possibility you already have a PIN set up on your device
and don’t remember. I
To set this option for your smartphone, access
Settings, Lock Screen & Security, and then PIN. Similar to setting a password, you will see a warning about
what happens if you forget your PIN. Input your PIN once, select continue, and
then again to confirm. Your device will return to the previous settings page to
confirm.
On an iPhone you can select within the same
settings whether you want a numerical PIN or an alphanumeric Password. On an
Android device, the PIN and Password are two different security options.
Pattern
The Pattern security option is popular among smartphone users because it is easy to remember and inputting the set pattern design can be fun. A Pattern is considered a medium security option because many users may choose a simple design, however it is easy to modify a common design to a more secure pattern.
To set this option for your smartphone, access
Settings, Lock Screen & Security, and then Pattern. Similar to setting a Password, you will see a warning
about what happens if you forget your Pattern. Input your Pattern once, select Continue, and then again to confirm.
Your device will return to the previous settings page to confirm.
Fingerprint
The Fingerprint security option can be used
not only as method of unlocking your device, but also as an authentication
function for smartphone features, such as payment systems. You can use a set
fingerprint to authenticate payment on Google Pay, Samsung Pay, and Apple Pay
on older iPhones.
Some devices have a fingerprint scanner within
their home buttons, while others have the feature on their back panels. Several
newer devices have fingerprint scanners embedded directly in their
displays.
Smartphones typically require users to have a backup security option in place when setting up a fingerprint. You can select a Password, PIN, or Pattern as your backup.
The security level of this option is not clear, since functions such as fingerprint spoofing are possible, but not common. The fingerprint scanners on iPhones are considered more secure than those on Android devices, but the fingerprint scanner is now a rare option on Apple devices.
To set this option for your smartphone, access Settings, Lock Screen & Security, and then Fingerprint Scanner. Confirm your backup passcode and follow the device’s directions for recording your Fingerprint.
On most smartphones you will have to place your finger on the designated scanner location in several different positions for it to register your fingerprint. Do this until the progress is 100 percent. Select Done.
Once complete you will then see a Fingerprint
Scanner settings page, which shows how many fingerprints you have registered on
your device, the apps and services available for fingerprint verification, and
an option to disable or enable fingerprint unlock as your discretion.
Facial recognition
The Facial recognition security option is another method that can be used for both unlocking devices and as an authentication function. The security level of this option depends on the device.
Many Android devices allow users to set face verification for certain apps, but the feature is not considered safe enough for payment authentication. Newer iPhones have Face ID as their only biometric option for unlocking and secure authentication, including Apple Pay.I

Once complete, you will be prompted to enable the function. Select Turn On. You will then see a Face Recognition settings page, which allows you to manage your face data, set up app verification and disable or enable the function.
Iris scanning
The Iris scanning security option can be used for both unlocking your device and as a form of secure authentication for payment systems such as Samsung Pay and Google Pay. The feature; however, isn’t that common on smartphones. Many devices favor facial recognition over iris scanning.
To set this option for your smartphone, access Settings, Lock Screen & Security, and then Iris Unlock. Confirm your backup passcode and follow the device’s directions for recording your irises.
On most smartphones you will have to remove your glasses and possibly your contact lenses and then hold the device forward to allow your eyes to align with the viewfinder to scan your eyes. Once complete, you will be prompted to enable the function. Select Turn On.
You will then see a Face Recognition settings
page, which allows you to manage your face data, set up app verification and
disable or enable the function.
Voice Detection
The Voice detection security option is a little known function that is available not so much for security, but rather for convenience. Users can set up Voice Match so that the Google Assistant on their smartphone will respond only their voice. Subsequently, you can set up Unlock with Voice Match to wake and unlock your device by saying “Ok Google.”
To set this option for your smartphone, access Settings, Lock Screen & Security, and then Smart Lock. Confirm your backup passcode and then select Voice Match. Select Access with Voice Match to record your voice for user with Google Assistant.

Once back at the “Ok Google detection” settings page, select Unlock with Voice Match and confirm the prompt acknowledging the feature’s limitations. It details that after a few failed attempts, users will have to input their backup passcode to access their device.
Once set, if you say “Ok Google,” your
device’s resting screen will turn on and go directly to Google Assistant,
waiting for further instruction. Many users may not find this function useful
unless they are avid users of Google Assistant.
More Tips to Manage Your Smartphone Passcode
Users must set a backup passcode to enable a biometrics feature, such as fingerprint unlock or face unlock, but you can also use the biometrics feature as a backup up happen to forget your passcode. As long as your smartphone hasn’t been restarted you should be able to use your biometric options to access the device without a passcode.
The Smart Lock option that enables voice detection has other functions that allow your device to remain unlocked in designated safe spaces. With Smart Lock, you can set your smartphone to remain unlocked while on your person, when connected to Wi-Fi in trusted locations, or when in a location with another trusted device connected to the same Wi-Fi.
Register your device with the manufacturer if they offer such a service. You will need to create a username and password (like the Samsung ‘Find My Mobile’ option), which you can use to log in and make remotely make changes to your device.
Connect your Google account to your phone so you can always confirm that your device is yours if prompted.
Backup the information on your smartphone so that you will have all of your data in the event you have to factory reset your device due to not knowing the passcode.
