2. Basic Measures: Conventional Methods to Protect Online Privacy and Security

Before discussing PIA S5 Proxy, let's first understand some basic protection measures. 

First, using strong passwords and changing them regularly is a basic way to keep your accounts safe. 

Secondly, enabling biometric technologies such as two-factor authentication and fingerprint/facial recognition can further increase account security. In addition, it is also very important to keep the iOS system updated and to promptly patch known security vulnerabilities.

When browsing the web, it is recommended to use the built-in Safari browser or other security-verified browsers, which generally have better privacy protection and security. At the same time, avoiding clicking on links from unknown sources and downloading unverified applications are also important measures to protect device security.
