Hello @yoyodynedataand @catharine.dill,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
I am sorry about the issue you are having. This is because you have a password for LastPass stored in your browsers in-built password manager. Please delete it and you should no longer have this issue.
Please let me know if this worked or if further assistance is required.
Thank you,
Henry | Customer Care
Me too. It autofills with my LastPass password, instead of the specific password I created for the site.
