@Eric25 it sounds like you're trying to delete the entire account and all Vault data? If so, please follow these instructions:https://support.lastpass.com/s/document-item?bundleId=lastpass&topicId=LastPass%2Fdelete-account.html&_LANG=enus&language=en_US
LastPass will keep a backup copy of your encrypted vault data for 30 days in case you change your mind. After that point the data is erased permanently.
