I’d want a ‘Unknown login’ has your account been logged in from Norway? Send an email/text asking if this was them and prevent that Norway guy from logging in until you’ve verified it. Similar to how steam works with trusting computers to use your steam account, if you get a new machine it’ll want you to verify it and ‘name it a friendly name’.
Why not in-cooperate some kind of 2 factor auth with the existing ROBLOX app? That way you know only the person currently holding that device can authorize new machines or an unexpected login from Norway or to be extra secure, authorize purchases over 1000R$. A machine cap that you can set so the maximum times you can be logged in at once (e.g. be logged in on your phone, tablet and computer) that way there’s no possible way of logging in to your account from a new machine (unless you de-authorize one from your existing machines).
Of course everything is optional but I’d personally want all of these on
Currently, I hate how insecure our accounts are, if someone has our password that’s it. They’re on and you’re screwed.
