Google Chrome has a password manager which allows us to save passwords and removes the burden of typing it again when we revisit a site. If you have by mistake saved a password on chrome and wanna remove it, then just follow these simple steps:
Click the Chrome menu 
on the rightmost end of browser toolbar.
Select "Settings".
Scroll to the bottom and click on "Show advanced settings".
Scroll down further and under the "Passwords and forms" section click on "Managed passwords". You will see a list of all the sites with their usernames and passwords saved ever on chrome.
In the Passwords dialog that appears, use your mouse to hover over the site whose password you'd like to remove and click the X that appears on the right. Its deleted.
