When it comes to Twitter, you’ll need to find the Twitter settings page online, then, under Data and Permissions, select Apps and sessions. Under Sessions, click on an individual device name and then Log out the device shown. Contrary to other platforms, your devices will be listed by operating system instead of by model and manufacturer. That means if you have several Apple or Android devices, it may be harder to identify exactly which one is which. If you want to be extra careful or just can’t be bothered to identify all your devices, you can always select Log out all other sessions and take care of all of them at once.
