Here are the steps I took to change my email address in LastPass.

 

  • In the upper right corner, click your account name and select Account Settings

  • Change your Account Email and click Update
  • LastPass will send an email to the updated email address. Open that email, copy the code, paste it in the Code field, and click Confirm
  • LastPass will prompt you for your Master Password. Enter it and click Confirm
  • LastPass will re-encrypt your data
  • Then log you off
  • Log in using your new email address
  • Your account will now reflect your new email address
