WhatsApp Web’s “Multi-Device” feature is incredibly convenient, but it also opens up a specific security vulnerability known as “Session Hijacking.” Because a device remains logged in even if your phone is offline, an attacker who gains access to your active web session\u2014either physically or via a malicious link\u2014can read your messages and scam your contacts without you ever knowing.<\/p>\n\n\n\n

Fortunately, Meta has built multiple layers of defense into WhatsApp. Here is how to audit your account, identify potential hijacking, and secure your WhatsApp Web session for good.<\/p>\n\n\n\n

\n\n\n\n

1. Audit Your Linked Devices Frequently<\/h2>\n\n\n\n

This is your first and most powerful line of defense. Every device currently logged in to your WhatsApp account is listed on your primary phone.<\/p>\n\n\n\n

    \n
  1. Open WhatsApp on your mobile phone<\/strong>.<\/li>\n\n\n\n
  2. Go to Settings<\/strong> > Linked Devices<\/strong>.<\/li>\n\n\n\n
  3. Look for any device you don’t recognize (e.g., a “Linux” computer if you use Windows, or a login from a city you haven’t visited).<\/li>\n\n\n\n
  4. Tap the suspicious device and select Log Out<\/strong>. This kills the attacker’s session immediately.<\/li>\n<\/ol>\n\n\n\n
    \n\n\n\n

    2. Beware of “QR Code Phishing”<\/h2>\n\n\n\n

    A common scam involves attackers sending you a link to a website that looks like WhatsApp Web but is actually a proxy. When you scan the QR code on the fake site, you aren’t logging in to your own computer; you’re giving the attacker full access to your account on *their* computer.<\/p>\n\n\n\n
