I was using Whatsapp Web on chrome, and I got the message "Whatsapp Web is already open in another computer or browser".

What should I do?

  • Well I've never used WhatsApp, but you'd think because of the nature of the app there would be a "invalidate all sessions" option in the settings. Try to look for that and then change your password. Commented Aug 12, 2016 at 14:45
  • It might also be useful to others to supply how you use WhatsApp, do you only use it over web or do you use it on your phone as well? Have you recently lost or misplaced your phone? If someone had your phone would they be able to unlock it and access your WhatsApp key store? Commented Aug 12, 2016 at 14:51

    Don't assume that you're safe from malware because you have iOS, that's a dangerous thought to have considering how many *nix kernel vulnerabilities have been coming out lately. Like I said previously, we don't have much to go on because it literally could be anything. Commented Aug 12, 2016 at 15:22
