WhatsApp users currently uninstall and reinstall the app, if they want to “log out” of the service.
WhatsApp is working on a new feature that could give users more flexibility while using the messaging platform, according to a report. A teardown of the latest WhatsApp beta release for Android smartphones reveals that the messaging service could soon allow users to log out of their account, even on their primary device. This will reportedly allow users to stop using WhatsApp for a while or switch to another account, without deleting the app’s data from their smartphone.
WhatsApp to Let Users Retain or Delete Data While Logging Out
Android Authority and AssembleDebug spotted a new Logout option, during a teardown of WhatsApp beta for Android 2.25.17.37. The feature appears to be in development, or the company could also be testing it internally. It is said to be found under Settings > Account, according to the publication.

The new logout option presents users with three options: Erase all Data & preferences, Keep all Data & preferences, and Cancel. Choosing the first option will delete all the chats from a user’s device, while the second option keeps them around in case the user logs in again.
If users select the Keep all Data & preferences option, WhatsApp will log them out of their account, but keep their chats, files, and other media on the phone. Users can quickly access all of your content as soon as you log in again.

This feature sounds quite handy for users who want to take a break from using WhatsApp, instead of deleting their account. Many modern messaging apps like WhatsApp do not allow users to “log out”, which means users have no choice but to uninstall the app from their smartphone if they do not want to use the app for a while.
