    Understand what a VPN does and does not do

    ~42s
    A VPN protects your traffic from being read by your internet provider, the WiFi network owner, or anyone intercepting data on the same network as you. It does NOT make you completely anonymous online — websites still know who you are when you are signed in to them. It does NOT protect you from phishing scams, malware, or viruses. It does NOT prevent websites from tracking you with cookies. Think of a VPN as a privacy tool, not a security tool — it hides your browsing. But it does not make you immune to scams.

    Quick Tip

    The most common legitimate reason to use a VPN is when using public WiFi at a coffee shop, airport, hotel, or library. On your home network, a VPN is generally not necessary for most people.

    Know which VPNs are trustworthy

    ~23s
    Free VPNs often make money by selling your browsing data — the opposite of what you want. Paid VPNs from reputable companies are more trustworthy. Three well-regarded options: Proton VPN (has a free tier with no data limits; paid plans start at $3.99/month) — ExpressVPN (widely used; around $8/month with a 30-day trial) — Mullvad VPN (strong privacy record; $5/month flat). Avoid lesser-known free VPNs from unfamiliar developers.

    Install and use a VPN on your phone

    ~28s
    Download your chosen VPN from the App Store or Google Play. Open the app and follow the setup. You will create an account and grant the app permission to set up a VPN configuration on your phone (iOS and Android both ask for this permission; it is normal). Once set up, tap "Connect." The VPN icon (a small key on iPhone, or a key symbol in the notification bar on Android) shows when the VPN is active. Tap "Disconnect" when you are done.

    When you should and should not use a VPN

    ~25s
    Turn the VPN ON: when using public WiFi anywhere outside your home, when traveling internationally, when you want to prevent your internet provider from seeing your browsing history. Turn the VPN OFF: when banking or using financial apps (some banks flag VPN connections as suspicious and may lock your account temporarily), when using streaming services that may block VPN access, when the VPN slows your connection too much for video calls.

    A VPN — short for Virtual Private Network — is software that encrypts your internet connection and routes it through a server in another location. When you use a VPN, websites you visit see the VPN server's location instead of your real one. Anyone watching the network you're on — your internet provider, or the owner of a coffee shop WiFi — can't read your traffic. VPNs are useful in specific situations. But you don't need one for everyday browsing on your home network.
