great tip for securing Last pass

Use a Dedicated Security Email Address

For additional security, you can have LastPass send security-related emails to a special security email address instead of your normal email address. For example, password hint emails, account recovery emails, and multifactor authentication disable emails will all be sent here.

This email should be an extra-secure email address only you know about – if someone gains access to your day-to-day email account, they won’t be able to access your LastPass vault without access to your security email account.
