Is there any way to password protect google chrome browser? So that I can do "Remember password" on sites browsing in chrome in a shared computer and others can't access it
Depending on your system you could encrypt your Chrome Profile Folder (TrueCrypt in Windows, equivalent ones on other operating systems)
Before starting chrome, you mount your encrypted archive, then use
chrome.exe --user-data-dir="<location to profile>"
to start the browser using that directory.
P.S.: You can put a specific link on your desktop with the parameter for the profile location, so others can use chrome with the default profile.
One more useful tool very similar to Truecrypt - Rohos Mini Drive. I'm using it's feature - Hide folder to password protect my Google Chrome profile - http://www.rohos.com/2010/12/how-to-password-protect-google-chrome-data-with-rohos-encryption-software/
Chrome's passwords are encrypted with your login password, at least on Windows, though very weakly. I'm going to have to say that it's a bad idea to use the browser's built-in password manager no matter what. Google Chrome can import Firefox's passwords even if Firefox's passwords are under a master password.
Use a dedicated password manager that is at least reasonably secure. The safest is probably KeePass because it's been around for quite a while. Lastpass is another option that is reasonably secure, but if you're working on the CIA, keep in mind that it hasn't been audited by any independent organization yet (KeePass hasn't been audited either, but it's open source, so thousands of people can and have read through the code for security flaws and those flaws are fixed very quickly).
In summary: if you're paranoid, use KeePass. If not, use LastPass.
You could try using the LastPass plugin to have an online and extremely secure password vault. Just turn off automatic login and your set. It even has the bonus advantage of a web interface and portability.
Use Discolock a freeware small utility, which password protect many applications.
On the Chrome toolbar click on the ‘+” sign to open a new tab left click on the “3” vertical dots at the far right with your mouse when the menu opens, click on “settings” the “search” bar will show a “navy blue chrome Icon” followed by the word “Chrome”, a vertical line, then chrome://settings
the menu that opens up after left or right clicking with your mouse on the word “settings” brings up a new menu that starts with the word “People” as a heading, followed by a vertical list starting with your Google sign in that shows “Syncing to XXXXXXX@gmail.com”, etc. (see pic)
From this list, click on the “Passwords” word Now you will see in the “address/search bar”: “Chrome | chrome://settings/passwords”
From here you take your mouse and left click and “Hold” on the nave blue chrome icon in the “address/search bar”.
“DRAG” that “navy blue chrome icon” to your toolbar where you have your “other” shortcuts and VOILA !
YOU NOW HAVE A SHORTCUT TO YOUR PASSWORDS RIGHT ON YOUR TOOLBAR…
…it will now show a “navy blue ‘settings’ icon” with the word “Settings” next to it.
Now every time you open your Chrome browser, it will be there for you to access in “ONE CLICK”
Using this app, you can import all your Google passwords (since it's not clear how they're secured), and after importing consider removing them all as they're still stored in the cloud and you can see your of all passwords by going to https://passwords.google.com/
