How to hide your online status from everyone on WhatsApp?

WhatsApp has a feature that allows you to completely hide your online status. You can hide it quite easily through the application settings. 

Let's go! 

1. First you need to open the settings and go to the following path: "Account" → "Privacy" → "Last visit time and online status". 
2. After clicking on it, you will need to configure the ability to view the time of the last visit by selecting "Those who see the last visit". 
3. Then save all the changes made to view the status below.

If you decide to select "Nobody" in the first list and apply this setting below, then no one will see when you are online.
