Hi @marcelainfante5
Welcome to the LastPass Community.
In some cases the location ID can be generally identified in a nearby city. These are the major data centers used to route internet connections, so as long as you were 'nearby' Brooklyn, within a couple hundred miles of it, this may explain that location ID.
You may view your entire account history within your online Vault to confirm recent activity. Should you notice anything out of place, I suggest updating your account password to one that is complex yet easy for you to remember.
