How to remove your LastPass account
Be logged in on the site; then use the removal link. A good thing for a service such as Last Pass, for you wouldn’t want all those passwords to be present on their site for an eternity.

Helpful Trick: Removing online data
Publicly visible text/images often aren’t properly removed even when you succeed in removing an account. Try editing or removing them manually before removing the account itself. If you’re unsure what happens to your tracks: this can be found mostly in the Terms of Service/Privacy Policy; otherwise you can always contact LastPass and ask personally. By the way, removal requests don’t necessarily mean your data will actually be removed (e.g. due to legal obligations).
Helpful Trick: Remove third-party logins
If you signed up for LastPass using a third-party login such as Facebook or Twitter, you probably want to revoke all access from LastPass. Click here to find out how.
