My friend invited me to a Lastpasss family plan in November 2022. I did not have an account of LastPass at that time but I gave him my email address so he could invite me. And I forgot this thing so I even did not click the button in the inviting email to set my master password. I recollect the thing today, but I fail in recovering my account. The email says that my master password is "Generated Password", and the link in the inviting email is expired. It says "Your invitation link has expired. Ask your LastPass administrator for a new invitation." after I click it. So how can I recover my account? Is the friend inviting me my LastPass administrator? Or should I contact LastPass? But contacting them needs logging in LastPass either. So what should I do, could anybody help me?
