How does one set up and use ProtonVPN?

Setting up and using ProtonVPN is a straightforward process. First, one needs to sign up for an account on the ProtonVPN website, choosing a plan that suits their needs, which includes free and paid options. After creating an account, they need to download the appropriate VPN client for their operating system (Windows, macOS, Linux, iOS, Android). Upon running the application, they log in with their ProtonVPN credentials. Once logged in, they can connect to a server by selecting one from the list of available countries or using the Quick Connect feature that automatically chooses the best server. It's essential to ensure that the connection is established before browsing, as this guarantees data encryption and protection of privacy online. After finishing their internet session, they disconnect from the server through the client to end the VPN protection.
