Hello @coinflips10,
My name is Alejandra and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
I apologize for any inconvenience this is causing you. If you have not login in the account with the device mentioned via the app and using biometrics the system will not allow you to recover using iPhone. However, I checked your account and the account seems to be empty.
In this case, the best option will be a reset account process. You can find more here: https://lastpass.com/reset_account.php

Kind Regards,
Alejandra
