How to Log Out of WhatsApp on iPhone

There is no direct sign-out button in the WhatsApp app on your iPhone. You can follow these steps to remove your account from the device without losing your data.

1. Open WhatsApp, go to Settings, and select Linked Devices to log out of any active sessions on computers or browsers [0:11].
2. Navigate to Settings, tap Chats, and then select Chat Backup to ensure your message history is fully saved to iCloud [0:32].
3. If you truly need to remove the account from your phone, go to Settings, tap Account, and select Delete My Account to proceed with the final removal [1:02].

Ninja Tip: If you only want to stop using the app temporarily without deleting your account permanently, simply uninstall the app from your iPhone home screen after performing your iCloud backup. You can then reinstall it later and restore your messages from that same iCloud backup without ever touching the “Delete My Account” button.

If you need to completely erase your iPhone to its original state, go to Settings > General > Transfer or Reset iPhone > Erase All Content and Settings.
