Hello @james48246,
My name is Alejandra, and I am happy to assist with your inquiry and appreciate you contacting LastPass Support!
I apologize for all the inconvenience this is causing you. I noticed that there were a lot of attempts to receive an SMS but it seems that the system reached the limit of SMS. I was checking that you use it for the multifactor authenticathor, however, the SMS is a back up option. My suggestion if you are not able to access will be to create a case so we can disable the multifactor authenticator for you after answering some security questions.
Kind Regards,
Alejandra
