How to Switch Facebook Account on Mobile

Switching Facebook accounts on a phone can be done in two ways: log out of the current profile and log into another one, or choose a saved profile on the login screen if it has already been added to the app. The important point is not to confuse switching accounts with deleting a profile, deleting the app, or changing the owner of a Page.

If the phone is personal, a normal log out and log in is usually enough. If the device is shared, work-related, or already has several saved profiles, also check saved logins, notifications, Messenger, Instagram, and access to Pages or Business Manager.

First, check which account is currently open

Open the Facebook app and tap the profile picture or menu. Check the name, avatar, email or phone number if shown, and the Pages and groups available from the profile. This helps avoid logging out of the wrong profile, especially when similar accounts are used on one phone.

If the account is connected to a business Page, ad account, or Business Manager, make sure you know the login, password, and two-factor authentication method before logging out. Losing access to a personal profile is unpleasant, but if it manages work assets, the consequences may be more serious.

If you are switching profiles because of an advertising setup, it is useful to understand which assets are linked to the current account. You can review the section with Facebook Business Manager accounts to separate a personal profile, BM, Page, and ad account.

How to log out of the current account

In the Facebook app, open the menu, scroll down, and tap Log out. The app will return to the login screen, where you can choose a saved profile or enter the details of another account.

If the old profile remains on the login screen, it does not always mean you are still logged in. Facebook often shows saved login information for quick access. If the phone is shared or you do not want the profile to open with one tap, remove the saved login information.

To remove saved login information, open security settings and the saved login section. There you can remove the profile from the device so the app no longer offers quick login without entering details.

How to log into another account

On the login screen, enter the email, phone number, or login of the other account, then enter the password. If two-factor authentication is enabled, Facebook may ask for an SMS code, authenticator app code, push confirmation, or another available verification method.

Do not rely only on SMS in advance. Different accounts may use different protection methods: an authenticator app code, confirmation on another device, backup codes, or identity checks. Before switching accounts, make sure the second profile is actually accessible.

After logging in, check that the correct account is open: name, avatar, notifications, Pages, groups, and connected Messenger. Sometimes users think they switched profiles, while Messenger or connected Instagram still uses the old account.

What to do if there are several accounts

If you regularly switch between several profiles on one phone, keep saved logins under control. Quick login is convenient, but it should not create confusion: you need to know which profile is active and which account receives which notifications.

Facebook and Instagram may be connected in Accounts Center. This is not the same as “several Facebook accounts”, but connected settings can affect login, shared features, notifications, and security. If something looks wrong after switching accounts, check Accounts Center.

If one of the profiles is used for Pages, ads, or team work, do not give the phone to other people with saved login enabled. It is better to use separate roles, permissions, and 2FA than rely on the hope that nobody opens the wrong account by accident.

Common mistakes when switching accounts on a phone

The first mistake is deleting the app instead of logging out. Deleting the app may remove some local data from the phone, but it does not delete the Facebook account and does not always solve login issues.

The second mistake is forgetting about Messenger. If you log out of Facebook, Messenger may still remain open under the old profile. After switching accounts, check both apps if you use them together.

The third mistake is switching accounts without checking access to email, phone, or 2FA. If Facebook asks for confirmation and the required phone number or authenticator app is unavailable, login may get stuck.

If you do not want to switch profiles but want to permanently remove the old account, that is a different task. Use the separate guide on how to delete a Facebook account through the app.

The conclusion is simple: to switch Facebook accounts on a phone, log out of the current profile, remove saved login if needed, and log into another account with available email, password, and 2FA. After logging in, check Messenger, Accounts Center, and work assets if the profile is connected to Pages or ads.
