A VPN (Virtual Private Network) is a technology that encrypts internet data traveling to and from your device, concealing it from anyone who may want to intercept it. VPN software can be installed on your smartphone, tablet, or computer, and it sends your data in a scrambled format that is unreadable to others. Encryption is necessary because you send personal information through the internet, which can include your browsing history, passwords, and credit card information. A VPN hides the demographic data sent with your internet activity, so you cant be tracked.

To set up a VPN on an Android device, you can use the built-in VPN client that comes with Android (PPTP, L2TP/IPSec, and IPSec) . Devices running Android 4.0 and later also support VPN apps. You might need a VPN app instead of the built-in VPN for several reasons, such as to configure the VPN using an enterprise mobility management (EMM) console, to offer VPN protocols that the built-in client doesn’t support, to help people connect to a VPN service without complex configuration, or to run a separate VPN for the personal profile or work profile.

Using a VPN on your smartphone is essential to keep your personal information safe while using the internet. With a VPN, your online activities are private and secure, even from your internet service provider. Public Wi-Fi hotspots are not secure, and any knowledgeable hacker can access any data being sent over that connection, including yours. Setting up a secure VPN on your smartphone can help you stay safe from identity theft and other cyber dangers.
