i recently exported and deleted my account, then recreated my account but I cannot remember my password .
the error i get when trying to recover is that the Lastpass browser extension hasn't been installed - I have tried account recovery on both Edge and Chrome.
If there aren't any sites stored in your account yet, you could instead Reset the account. This will allow you to start over with a new empty Vault and new master password. If you have access to the email address you can reset your account by following these steps https://support.logmeininc.com/lastpass/help/reset-your-lastpass-account-lp010066 When asked if you know your Master Password select No.
