You can use your Apple Watch to unlock your Mac computer’s screen saver and approve authentication requests from macOS and other apps, without having to enter a password. This feature is called Auto Unlock and Approve with Apple Watch, and it requires that you have an Apple Watch with watchOS 6 or later, a Mac with macOS Catalina or later, and that both devices are signed in with the same Apple ID using two-factor authentication. To turn on this feature, you need to go to System Preferences > Touch ID & Password > Apple Watch and enable the option next to the name of your watch. Then, whenever you wake your Mac from its idle state or an app requires authentication, you can double-click the side button of your Apple Watch to unlock or approve the task. References:

According to the Apple Support website, you can manually configure a VPN connection on your Mac by choosing one of the following VPN protocols: L2TP over IPSec, Cisco IPSec, or IKEv2. L2TP (Layer 2 Tunneling Protocol) is an extension of PPTP (Point-to-Point Tunneling Protocol) used by internet service providers to enable a VPN over the internet. IPSec (Internet Protocol Security) is a set of security protocols. IKEv2 (Internet Key Exchange) is a protocol that sets up a security association in IPSec. The other options, SSTP, Wireguard, and OpenVPN, are not supported by macOS System Settings, and require third-party software to use. References: 1 Set up a VPN connection on Mac - Apple Support
