A modern smartphone based on Android is not just a device for making calls, but a full-fledged digital center, tightly integrated with the Google ecosystem. Account links purchase history, contacts, photos and application settings to the device. However, life situations often require a change of owner or temporary use of the gadget by another person. A reasonable question arises: how to correctly log in to the system as a new user without losing the important data of the previous owner or without disrupting the system?
The procedure for changing a user varies depending on whether you just want to add a second person for temporary access or completely transfer the phone to other hands. In the first case, it is enough to use the function guest mode or create a new profile. In the second, you will need a complete reset or deleting the old account through the security menu. Incorrect actions can lead to the device being blocked by protection FRP (Factory Reset Protection), so it is important to understand the difference between simply changing the profile and completely re-registering the device.
In this article we will analyze in detail all the available account management methods. You'll learn how to add a second Google account email synchronization, how to switch between users on tablets and smartphones that support multi-user mode, and how to safely delete your old profile before selling your gadget. We will pay special attention to the nuances of working with Samsung, Xiaomi and clean Android, since the interfaces of manufacturers may have significant differences.
Adding a second account without deleting the current one
The easiest and safest way to use your phone under a different name is adding an additional account to an already existing system. This feature allows you to simultaneously have access to personal mail, work documents or family members' accounts. At the same time, applications installed by the main user remain accessible, although the data inside them (for example, progress in games or drafts in instant messengers) can be divided.
To get started, you need to go to the system settings. Find the section responsible for user management. Depending on the version Android and shell of the manufacturer, this item may be called differently. Typically the path looks like this: Settings → Accounts and synchronization or Settings → Users and accounts. Here you will see a list of all current bindings, including Google, social networks and manufacturer services.
Press the button Add account. The system will prompt you to select the type of service. For a full app store experience and contact synchronization, select the Google logo. You will be prompted to enter your email address and password. If two-factor authentication is enabled on your device, you will need to confirm your login via a code from SMS or an authenticator application.
- 📧 Personal profile: allows you to separate work and personal correspondence in one device, quickly switching between them in the Gmail or YouTube applications.
- 👨👩👧👦 Family access: convenient for parents who want to control their children's purchases or give them access to certain content without sharing a master password.
- 💼 Corporate login: required for employees who use Google Workspace service accounts to access internal company resources.
After successful data entry, the new profile will appear in the list. It is important to note that adding an account does not replace the main one. When you launch applications such as Google Play or Google Photos, the system may ask which account to use as the default. You can set priorities manually in the settings of each application.
⚠️ Attention: Adding an account automatically starts data synchronization. If your phone is low on free memory, downloading photos and files from a new user's cloud can quickly fill up the storage. Disable the synchronization of heavy media files in the settings of the newly added profile.
Use the "Quick switch" function in the notification shade (if available on your model) to instantly change the active Google account for services without going into deep settings.
Using the multi-user and guest mode
Function several users turns your smartphone into a real personal computer, where each person has his own isolated space. Unlike simply adding an account, this creates a completely separate environment: your own wallpaper, your own settings, your own installed applications and your own files. The main owner of the device acts as an administrator and has rights to delete other profiles
To activate this feature, go to Settings → System → Multiple users. On some devices, such as Samsung or Huawei, this option may be hidden in advanced settings or only available on tablets. If the switch is active, turn it on. After this, a profile icon will appear in the notification shade, clicking on which will bring up the user selection menu.
You can create a full one second user or use the mode Guest. Guest mode is ideal for temporarily sharing your phone: a friend can call, look at photos or use a navigator, but will not have access to your messages and banking applications. After exiting guest mode, all data created in this session is automatically deleted.
| Profile type | Access to owner contacts | Installing applications | Saving data after exit |
|---|---|---|---|
| Owner | Full | Yes, without restrictions | Yes, always |
| User | No (isolated) | Yes, your applications | Yes, before deleting the profile |
| Guest | No | Temporarily | No, deleted |
Switching between profiles occurs instantly, but active applications in the previous profile can be suspended to save RAM. This is convenient if you give the phone to a child: he plays his version of the game without disrupting your progress, and does not see your notifications from instant messengers.
Full account replacement when transferring the device
The situation changes dramatically if you plan to sell the phone, give it to a relative, or just want to start using the device from scratch under your only account. In this case, simply adding a new profile will not work, since the old account will remain tied to the phone's hardware. This may cause problems with security and synchronization.
The most reliable way to log in under another account as the sole owner is to perform reset to factory settings (Hard Reset). Before this procedure, it is critical to delete your old Google account manually for the theft protection to work. If you simply reset the settings without logging out of your account, the next time you activate the phone, it will require the password from the old profile (FRP lock).
The correct algorithm of actions looks like this: first go to Settings → Accounts, select the old Google profile and press Delete account. Confirm the action by entering your screen unlock password. Only after the list of accounts is empty can you perform a reset. To do this, go to Settings → System → Reset settings → Delete all data.
⚠️ Attention: If you If you forgot the password for your old account and cannot delete it through the menu, resetting the settings through the Recovery Menu (using the volume and power buttons) will block the device with Google protection. Unlocking a phone without data from an old email is extremely difficult and often impossible using legal methods.
After the reboot, the phone welcomes you as a new device. During the initial setup stage (Setup Wizard), you will be able to enter your new account information. All applications, settings and files will be downloaded again, associated exclusively with the new owner. This guarantees complete confidentiality and the absence of synchronization conflicts.

This happens because the application was downloaded under an old profile, and the current active profile does not have rights to it. The solution is simple: delete the problematic application and download it again from Google Play, being authorized under a new account.

- 🌐 Network check: make sure the connection is stable; try switching from Wi-Fi to mobile data or vice versa.
- 📱 Software update: An outdated version of Android may not support new Google authentication protocols, check for system updates.
For advanced users who are faced with software issues failures, it is possible to reset account settings through the engineering menu or ADB, but this requires high qualifications. It is better for an ordinary user to limit himself to standard methods of deleting and re-adding a profile.
⚠️ Attention: Settings interfaces may vary depending on the version of Android and the specific phone model. If you do not find the described menu items, use the search in the settings (magnifying glass icon at the top of the screen) by entering the query “Accounts” or “Users”.
Successful account change depends not only on entering the correct password, but also on first clearing the device of old profile bindings in order to avoid license conflicts and security locks.
