Can I see login history on Instagram?
The web version of Instagram allows you to see your login history just like the app. ... In the menu that pops up, select “Login Activity.” Instagram will then show you a list containing all login locations from which you (or someone else) logged into your account.
Does Instagram notify when you login from another device?
If someone logs in to your account from an unknown location or device, we'll send you a notification to confirm it was you. If it wasn't you, you'll be able to quickly reset your password to make sure no one else can log in to your account.
