Instagram provides a platform where you can check the devices that have accessed your Instagram account. To check login devices of your Instagram account, you will have to open the Instagram application. Then you have to click on the Settings option. There you tap on Account Center. After that, you have to tap on **Password and Security**. Lastly, you will have to click on **Where You're Logged In**. When checking for the devices, you have to be very careful. All unrecognized devices must be logged out.
In case you notice that another person is logging into your Instagram account without your authorization, you should change your password. Two-factor authentication must also be activated. Your Instagram account will be more secure if you do so.
