I contacted lastpass support, as we got no response here.
The case is under review by their developers now:
Thank you for your reply.
I got a response from our developers, so they said that it's been put under review and they have created a ticket in which they will be working on adding more authenticators. I'm attaching this ticket to your case so once it's resolved or developed we will let you know.
We appreciate your patience.
