Lastpass is a very popular service that allows you to manage your passwords and form data, allowing you to easily fill inane forms with the click of a button.
Lastpass has released a Google Chrome extension that will allow you to manage your passwords and forms from Google Chrome.
You can manage your entire account using this extension. You can add new sites, create notes, fill form among other things.
Please note that this extension is not yet full stable. The extension did crash twice but due to way chrome works it did not crash the entire browser.
Definitely worth trying out if you are a lastpass user and have been using Google Chrome.
You will need to use the development version of Chrome to make use of this extension.
