These VPN tutorials offer useful guidelines for getting started using a VPN service on an iOS device.
You can find setup tutorials for other platforms and devices (Windows, macOS, Android and other) here.
NordVPN’s app for iOS is the fastest and most straightforward way to configure the VPN service on your device. This guide explains how you can download, install and sign in to the app. It also shows different ways how you can choose the most suitable server and connect to it. In addition, it explains various settings, such as Kill Switch, Smart Reconnect and more.
By default, the NordVPN app for iOS uses the IKEv2/IPsec protocol. This robust protocol remarkably increases security and privacy by employing very strong cryptographic algorithms and keys. NordVPN uses NGE (Next Generation Encryption) in IKEv2/IPsec. The ciphers used to generate Phase1 keys are AES-256-GCM for encryption, coupled with SHA2-384 to ensure integrity, combined with PFS (Perfect Forward Secrecy) using 3072-bit Diffie Hellmann keys. IPsec then secures the tunnel between the client and server with the strong AES256.
The app has all the necessary configurations set by default, so you can install and run it right away. It also gives plenty of freedom to adjust the settings for your particular requirements.
If you like to be in charge of the entire VPN setup process, you can configure the chosen security protocol manually by following these tutorials. However, please note that some of the protocols are not recommended for general use.
OpenVPN is a mature, secure and robust open-source protocol, which works with a wide variety of cryptographic algorithms. We use OpenVPN in NordVPN apps for other operating systems by default as it is considered to be one of the best protocols in the industry.
If you want to set up the IKEv2/IPsec protocol manually instead of relying on the NordVPN app, this guide will walk you through the required steps.
