The Facebook iPhone app can store multiple account logins and let you switch between them, although the exact account-switching controls can change as Meta updates the app.
- Open the Facebook app and go to its menu/profile controls.
- Use the current account-switching or profile/account option to add another Facebook login.
- Sign in to the additional account through Facebook’s normal authentication flow.
- When you need the other account, return to the account/profile switcher and select it.
- Enable two-factor authentication on each account and review saved-login settings, especially on a shared iPhone.
Accounts versus profiles
Facebook can also let one account manage additional Facebook profiles. Those are not necessarily the same thing as signing into two completely separate Facebook accounts, so check which identity the switcher is showing.
Notifications
Multiple signed-in identities can generate notifications that reveal account names on the Lock Screen. Adjust iOS and Facebook notification previews if privacy matters.
Saved credentials
Removing an account from the app’s switcher may not delete the Facebook account itself. Likewise, logging out does not close the account. Read the prompt before choosing remove, log out, deactivate, or delete.
Avoid third-party cloning apps
Do not install unofficial “dual Facebook” or credential-management apps simply to run another account. Use Facebook’s supported account/profile features or a browser session instead.
Password managers
If the accounts have different strong passwords, store them in a reputable password manager rather than reusing one password for convenience. Apple’s password features can also help fill saved credentials while keeping the accounts distinct.
