Does LastPass support webOS 3.0 on the HP Touchpad?
Yes, LastPass does support webOS 3.0 on the HP Touchpad, although there are some known limitations.
You can install the LastPass app directly on your Touchpad with this link: https://lastpass.com/lpwebos.ipk.
Please note that in order to download and run the app, you need to have Preware installed on your device: http://preware.org/#/index/.
You cannot use the virtual keyboard to fill forms in the embedded LastPass browser. For example, if you have a site that has a login with a security question that you need to type out, we recommend launching this in your default browser and copy-pasting your generated password from the LastPass app to the default browser.
