When you log in to your LastPass account via desktop or mobile device while you have an Internet connection, you are creating a locally cached version of your encrypted data to the local drive. This is the data that LastPass loads when you log in to LastPass while offline. Any LastPass web browser extension, desktop app, or mobile app can be logged into without an Internet connection, and will default to offline mode when no connection is present, if allowed to do so.
