Are you fed up of entering your Facebook password multiple times a day? Facebook provides a simple way to skip this step. Login to your Facebook account and click on the arrow next to 'Home' on the top bar.
Select account settings and it will open 'General' settings. Now, click on Linked accounts and select one of the account providers from the drop down box (includes Google, My-Space , Yahoo, openID and verisign) and click on 'link new account'.
You will need to provide your Facebook password to confirm the action. Next time around, Facebook will not ask for your password if you are logged in to your linked account on the same browser.
