VPN (Virtual Private Network) is a connector that allows, through a secure extension, the connection of a device to networks on the internet, allowing encrypted data to be sent and received to protect the user's information and location while connected to a public or private network.
This same security system can also be integrated into our smartphone so that, when we connect to any Wi-Fi network, no one can steal our data because it will be encrypted. Furthermore, it would prevent our real location from being revealed, as the VPN would disguise our IP address.
Although the networks our mobile phones use, whether public or private, are quite secure, it's always wise to take certain precautions to prevent our information from being used by unauthorized parties. That's why Android allows you to establish these types of connections. Below, we'll discuss this in more detail and explain how to configure, create, and connect to a VPN from your Android phone , step by step, including the necessary protocols.
What is a VPN and what is it used for on your Android smartphone?
As we explained earlier, a VPN is a tool that allows you to securely configure your internet connection by encrypting the information transmitted while browsing. This way, when you access certain websites, your IP address will be protected from potential theft of important data.
This technology is commonly used in companies to allow their employees to continue working from home, since by encrypting their private IP address they can connect to the corporate network while masking their location and can access their resources without any problems.
One of the advantages of using a VPN connection is the impossibility of tracking, since our IP address is "disguised" every time we connect to the network. This allows us to access information that is only available in certain countries, for example, when downloading certain applications, software, or files.
However, it's important to keep in mind that many services are not entirely reliable and can track our information, such as by "remembering" our passwords . When this happens, they are actually compiling usage statistics and profiles that they can sell to certain advertising or consumer research agencies.
Another thing to consider is that encrypting our data duplicates the information and therefore increases internet usage . That's why, with a slow connection, browsing speed becomes even slower. However, there are many reasons to continue using this type of connection.
For example, when we travel and want to access the web with our cell phone, our IP address will automatically be blocked because it is not authorized, making it necessary to have a VPN connection on our device; or in another case where you just want to connect to international services to access and download information without being blocked.
But most importantly, we must protect our data while constantly browsing the internet. Even if we only use a private network, we run the risk of being tracked, which encourages us to use these extensions, which use the following protocols to function:
- PPTP/MPPEThis server operates using the Microsoft Point-to-Point Encryption (MPPE) protocol. Its encryption capabilities are 40-bit and 128-bit.
- L2TP/IPsecIt is capable of providing the level of protection thanks to its L2TP tunnel protocol, but it does not encrypt the information itself.
- IPsecKnown as Internet Protocol Security, it has two encryption methods: transport and tunnelIt can encrypt up to 56 bits and 168 bits (triple DES), allowing for better security through algorithms and a more absolute authentication system.
The protection of your data is based on encryption, that is, on the encoding of the encryption , and to achieve this a mechanism is used that, upon detecting any modification within that encryption, discards any anomaly.
This technology also applies to your smartphone. Many people have antivirus software, but having a VPN is extremely beneficial as it will keep you protected when connecting to public Wi-Fi networks . That's why Android has long offered the ability to create a private network from the device.
Alternatively, you can also download an app that performs this function . Generally, VPN apps encrypt your data, and their setup is very simple, which we'll explain below.
Steps to create and configure a Virtual Private Network on your Android device
Using a VPN provides security for your information while browsing the web, but Android has made things easier and you can easily configure your phone.
Here's a step-by-step guide on how to do it :
- Open the "Settings".
- The options will be displayed "Wireless and networks" there you will mark "Plus".
- Then select the option "VPN".
- You will select the option "Add" and you will choose the type of VPN network.
- Next They will ask you for some information such as your name (you can write VyprVPN), in the field "Guy" and select the PPTP option, then enter one of the following server hostnamesTo continue, select "Save".
You can choose from some of the following server host names:
- To connect, open again "Settings" > "More" > "Wireless and networks" > "VPN" to open the VyprVPN option.
- The system It will ask you to enter your username and password, When finished, select "Save". You must remember to use uppercase and lowercase letters when entering the password.
- Finally, select the option "Connect" and ready. This way your device will be protected by a VPN.
Now, this process will allow us to browse securely on our mobile device. But remember that many apps offer VPN services for Android with an automatic setup process upon installation, making this task much easier.
