Advantages and disadvantages of the different security methods on your smartphone

Using a security or blocking method on our cell phone is not only a recommended action these days, it is necessary to protect our information and contents .

Fortunately, there are many ways to protect our phones, so here we analyze the advantages and disadvantages of each one so that you do not have pretexts and take care of all that gold mine that you charge on your phone.

Password: High security

One of the most hated, but also oldest methods to protect the cell phone (the computer, our accounts in portals and services, etc.) are the passwords.

Combining letters and numbers to access a device in order to protect our information is one of the oldest methods that exist, with a history of just over 50 years .

What are the disadvantages? If to protect our cell phone, passwords are a somewhat outdated method that, by its nature, requires too much effort and time to be used in a mobile device, where all actions are performed in seconds and sometimes with only one hand. Also, given the number of times we check our phones, passwords are too impractical .

What advantages does it have? Passwords are and will continue to be one of the safest blocking methods available . Of course, as long as you use a complex password that combines letters, numbers and symbols , and not words, sequences of letters or numbers or common references that can be easily guessed.

PIN: Medium to high security

A similar alternative, but much more practical and popular than passwordsis the PIN, especially because this can vary in length to reach a maximum of 16 digits , a figure probably excessive considering that what we seek when protecting our phones is a healthy balance between ease of use and an adequate level of security.

What are the disadvantages? If you use a very simple or obvious PIN , such as a special date such as anniversaries or birthdays, it can be easy to decipher, plus you have fewer options and combinations available than if you opt for a password.

What advantages does it have? If you use an appropriate combination of four or six numbers, it can be one of the safest and easiest methods to use on your cell phone. Also, if you want to encrypt your phone, it is one of the most compatible methods to validate and backup the data stored on your smartphone.

Pattern: Medium security

Although it is one of the most insecure methods that exist to protect the cell phone, curiously it is also one of the most used .

Its great popularity responds to its simplicity and ease of use , as well as being easy to remember and comfortable to use on the phone’s screen.

What are the disadvantages? Most people use very basic patterns, so it has been shown that it is very easy to replicate the pattern used in the phone following the mark or fingerprint left on the cell phone display, especially because being black is very easy to follow the trace left by the fingers. If you use this method, it is highly recommended that you constantly clean the screen.

What advantages does it have? If you create a sufficiently elaborate or complex pattern that covers the most points in the grid, it can be a very safe method to protect your cell phone.

Fingerprint: High security

One of the most advanced and secure cell security methods available are fingerprint sensors.

With just a few years since its arrival in the mass market, this technology is becoming faster and more precise , making it one of the most comfortable and practical security methods .

What are the disadvantages? Despite being the most advanced security method that exists in cell phones, it has also been proven that it can be circumvented through elaborate processes that copy and replicate our fingerprints. On the other hand, it is important to be careful not to get drunk or fall asleep near someone who wants to access your phone.

What advantages does it have? For the moment, it is the safest and most practical method to block and protectthe phone. It is also the easiest and fastest to use, and of course it does not require remembering complex passwords. Once you have tested your fingerprint as a way to unlock your phone, you will not want to use any other.

Face Recognition (Face Unlock): Medium Security

Although it never achieved much popularity, this method of facial recognition born four years ago with the arrival of Android 4.0 Ice Cream Sandwich is still present in some devices.

Although during its launch it generated many expectations for the innovative that it seemed at the time, very soon the Face Unlock proved to be very unsafe, since it was demonstrated that it was relatively easy to deceive it using a high resolution photograph , or even a video, of the person in question. However, although it seems a method of security in extinction, it has not yet died and could see a future return when technology evolves.

What are the disadvantages? Within the category of security biometric systems to which the Face Unlock belongs, this particular recognition method has not proven to be the most reliable and efficient, at least as we know it today.

What advantages does it have? Although currently it is not a particularly safe method, the Face Unlock has been improving, so now it is necessary to blink to identify yourself . On the other hand, if you are not a very public figure and it is not easy to find photographs of yourself, it can be a safer alternative than, for example, a PIN or even an unlocking pattern.

The evolution of this method is the Face Unlock 3D, which will be able to recognize textures on the skin, profiles and other features that would make it almost impossible for a third person to impersonate you.

Other security methods for your smartphone

Of course, these security methods for your smartphone are not the only ones, but they are the most effective and popular.

Other ways to protect your cell phoneinclude methods of blocking via Bluetooth, Wi-Fi (with the help of apps like SkipLock ) and even NFC, with the possibility of using a wearable as your smart watch to unlock your phone.

Although they can be potentially unsafe, Bluetooth or Wi-Fi unlock methodshave the advantage of giving you more freedom of use when you are in a controlled environment.

For example, if you are someone who uses voice commands a lot, unlocking via Wi-Fi or Bluetooth will be much more convenient, since with any of these methods you can use them more easily without having to unlock the phone manually every time make a consultation or action.

In this way, your cell phone will always be unlocked when you are close to it(if it is linked to another device via Bluetooth), blocking only when you get away, or when you disconnect from your trusted Wi-Fi network.

Another security method for smartphones that made its appearance this year was the iris scanning , which uses only the eyes as a means of authentication; however, the technology is still too young to evaluate the benefits or disadvantages it will bring as a security method for our phones.

Undoubtedly, the best unlocking method for our cell phones today is fingerprint sensors , a technology that will continue to be popular in the following years, especially now that it has matured and is faster, safer and more efficient than ever.
