Add support for LastPass Authenticator

[JacobDB]

When using LastPass Authenticator, it's very difficult to log in. While logging in, I need to have the app open on my phone, log in to Hyper, and very quickly hit "Approve" in the app. Even then, it fails 50% of the time. There should be at least a 5-10 second wait before failing, while it waits for approval from the app.
