Deactivate Viber account on different device As I lost the access code that Viber sent to me, I cannot sign in my Viber account. I signed in on another device. Now, I want to deactivate the account, so that the device holder cannot get my messages and conversations.
Refer to Viber's official guide on how to Deactivate your Viber account (Mobile):


  
  Open Viber
  Enter the More Options menu
  Select Settings
  Select Privacy 
  Select Deactivate Account
  
  
  Deactivation can only take place within the application. If you have
  uninstalled Viber and would like to deactivate your account, you will
  need to re-install Viber in order to do so.
