What is a VPN, and do you need one?

A VPN (virtual private network) encrypts the connection between your device and a VPN server. Your internet provider and others on the same network, such as public Wi-Fi, can no longer see which sites you visit, and websites see the VPN server's IP address instead of yours.

You may want one if you often use public Wi-Fi, want more privacy from your internet provider, or travel and want to reach your usual services. A VPN does not make you anonymous and does not protect you from phishing or malware, so keep your other security habits too.

Logins are a separate job. A password manager keeps a different password for each account, fills it in for you, and is worth having on public Wi-Fi or if a phone goes missing.
