Hello @Lenny Schafer,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
Do you want to delete all items in your vault? A fast way to do that is to reset the account.
If you want to choose which items to delete, you can follow the instructions from this article.
Please let me know if this worked or if further assistance is required.
Thank you,
Henry | Customer Care
