Hello @lenword2,
My name is Henry and I am happy to assist with your inquiry, and appreciate you contacting LastPass Support!
Name is simply how you can identify this item. For example if you have 2 different bank accounts, you can name one as "work bank" and other as "personal bank". This is only for you to identify them and has no impact on how you log in on this website.
Username is how you log into the site. This one does depend on how you log into this website, most sites use your email address but other websites will assign a different username.
Please let me know if this helped or if further assistance is required.
Thank you,
Henry | Customer Care
