Logging out of Instagram access on another device means removing the session that was active on that gadget. For this, there is a 'Where you're logged in' feature that displays all devices connected to the Instagram account and allows for remote sign-out.
This tool is available in the Security section of the Meta Accounts Center. Connected devices, whether smartphones or computers, are listed with an approximate region indicated based on the IP address used during login.
By viewing the list of devices associated with Instagram, the user can choose to log out only from the phone from which they want to remove the account, or remove access from all previously connected devices simultaneously.
Furthermore, changing the password in Instagram will also lead to the account being logged out on other devices. This is a security measure implemented by Meta to protect accounts in case of unauthorized access with an old password.
The ability to remotely log out another person's account requires having access to their profile, meaning knowing the username and password. It should be noted that accessing someone else's account without permission is a violation of privacy.
Removing another person's Instagram account is only possible when using their credentials. If you or another user do not have access to the email address or phone number registered for password recovery, remote account blocking is not possible.
The only exception to the platform's rules is in cases of the owner's death. In such situations, you can notify Instagram of the person's death and request the deletion of the account or conversion of the profile into a memorial.
An Instagram account can be used simultaneously on five devices. Nevertheless, it is strongly recommended to activate two-factor authentication and take other measures to enhance the security of your Instagram.
Users can detect suspicious activity in their Instagram by checking connected devices using the 'Where you're logged in' feature in the Meta Accounts Center. This section also provides a list of logins that the platform does not recognize.
An alternative method is checking the 'Account History' in the 'Your Activity' menu. This section in the main application menu shows the history of actions performed using your account. If you discover any changes that are unfamiliar to you, you should be cautious.
Logins or actions performed at a different time or in a different location than your place of residence may indicate that someone has accessed your Instagram. It is extremely important to know what to do if your Instagram is hacked: how to change your password and enable two-factor authentication.
