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?

  • Do you have more than one computer? Have you ever used it on any other computers? – sethmlarson Aug 12 '16 at 14:43

  • 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. – sethmlarson Aug 12 '16 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? – sethmlarson Aug 12 '16 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. – sethmlarson Aug 12 '16 at 15:22

Open Whatsapp in your handset.

Go to Options named "Whatsapp Web", Click on "Logout from all computers" & then try to login again.
