Changing a user from WhatsApp to Android is a task that millions of users face when buying a used phone, transferring a device to relatives, or the need to separate personal and work correspondence. Unlike social networks, where you can simply switch between accounts, the messenger is tied to a phone number, which complicates the process. This article will look at all the legal ways to change a user - from a basic exit from a profile to a complete data reset with saving chats.

It is important to understand: WhatsApp does not support multi-user mode in one application. Each phone number = separate account. If you need to switch between two profiles, you will have to either log out/log in again, or use WhatsApp Business as a second messenger. We will look at both options, and also tell you how to avoid data loss when changing users.

The article is relevant for all versions Android (from 8.0 to 14) and the latest updates WhatsApp (including beta versions). If you are using WhatsApp Web or WhatsApp Desktop, instructions for them are given in a separate section.

1. Preparing to change the user: what you need to do BEFORE logging out of your account

Before changing the user in WhatsApp, follow the required steps so as not to lose important data. The messenger does not save chats on servers - the entire history is stored locally on the device. If you simply log out of your account, new messages will be assigned to another number, and old ones may disappear.

This is what you need to do without fail:

  • 📱 Create a backup copy of chats. Without it, when you change your number, you will lose all correspondence. WhatsApp has a built-in backup function to Google Drive or locally on the device.
  • 🔐 Export important media files to. Photos, videos and documents from chats are not always saved in backup. Copy them manually to Gallery or the cloud.
  • 📋 Write down or photograph the settings. If you administer groups or use WhatsApp Business, save the list of participants, message templates and other data.
  • 📞 Check the linked number. Make sure that you have access to the SIM card that is used in the current account (to confirm the exit).

Pay special attention backup. In WhatsApp it is configured in the menu ⋮ → Settings → Chat → Backup. If you have never made a backup, the system will prompt you to create it the first time you log out of your account - but it’s better not to risk it and do it in advance.

If you plan to transfer the phone to another person, it is also recommended clear cache WhatsApp to delete temporary files. This will free up space and speed up the messenger for a new user. This can be done in the Android settings: Settings → Applications → WhatsApp → Memory → Clear cache.

⚠️ Attention: If you use WhatsApp Business, before changing user, be sure to export the product catalog and message templates. This data is not saved in a standard backup and will be lost when you exit your account.

2. Method 1: Simply exit your account (without deleting data)

If you need to completely clear your phone of the previous user's data, use the following method.
