Unlike fingerprint and facial recognition, by default all telephones offer the possibility of entering a code security or password. Despite multiple security options offered by current smartphones, the PIN and password have not lost their central position.
Why do you always have to lock your phone?
For the security of your personal data and your privacy. By locking your phone, you are not protecting it from theft, no. It's just your personal data that you're securing, not the phone itself.
Your stolen device will probably never be returned to you simply because it contains a security code. The thief will try to unlock it, or have it done. Whether he manages to unlock it or not, you probably won't have it anymore. He'll get rid of it one way or another.
So remember that when you configure a security code, a password, a fingerprint or facial recognition to lock your phone, it's not the device itself that you're securing but rather your data. And this is very important.
Advantages of PIN and password lock
The PIN code (Personal Identification Number) is a sequence of numbers allowing access to a system. The password can contain numbers, letters and sometimes special characters. On a smartphone, both can be configured but only one can be used at a time.
The PIN code and the password are still today the safest ways to secure a mobile phone. If used correctly of course. However, like all security modes, they are not infallible.
Many users still use the PIN code, whether on Android, iOS or other mobile operating system, on smartphones or on vintage phones. It is a simple and easy to configure lock mode.
Locking a phone with a code or password offers many advantages. The main advantage is that, unlike fingerprint and facial recognition, your phone will never be unlocked without your consent.
Once configured, if it is kept well, you will remain the only person to know your PIN code or password. But for that it should not be weak as a code or password. To better secure your smartphone, always use difficult codes or passwords, even impossible to imagine, but which will be easy for you to remember.
Another advantage of locking a phone with a PIN or password is that you can change them at any time and as many times as you want. Just go to the security options of your device to configure a new code or password.
Disadvantages of PIN and password lock
Locking a phone with a code or password does not only have advantages. It also has disadvantages although not many, in my humble opinion anyway. The first drawback of these two locking modes is forgetfulness.
If you forget your PIN code or your password, that's all you will no longer have access to your smartphone. Unless you are using an alternate mode. At this level the fingerprint reading and facial recognition make all the difference.
Locking a phone with a code or password has another disadvantage; visibility while typing.
Almost all devices hide the code during entry. But out in the open, that wouldn't prevent someone next to you from memorizing, or even writing down, the order in which you enter the numbers in your code or the letters in your password. This would require adopting an uncomfortable posture to be able to unlock your phone.
In public areas, be very careful before unlocking your smartphone using the PIN code or password, if you detect or suspect the presence of surveillance cameras. It may not be a surveillance camera, but a person pointing their smartphone camera at you.
No matter how fast you type your passcode or password, if you had been registered, the video can play at a very slow playback rate and there would be no secrets left. This would seriously expose your privacy.
Does locking your phone permanently secure your data?
The answer to this question is both yes and no. Some security systems are almost insurmountable, yes. But as you know, no locking system is foolproof. Fortunately, all phone manufacturers are working to improve the security of their devices to make them difficult, if not impossible, to bypass.
Some lock modes are more effective than others, but personally I prefer to lock my phone with a passcode or password. As for you, whatever lock mode you choose, make sure you always lock your phone.
