How do you let Chrome remember your password?

[Kenny]

When I click on the input text box of "Account", Chrome gives me a drop box for choosing my account from. But when I click on the input text box of "Password", nothing happens. How do I let Chrome remember my password? I don't want to input my password again and again.
By the way, in my Chrome advanced settings, "Enable Autofill to fill out web forms in a single click. ", "Offer to save passwords I enter on the web." are checked already.

When you log in like in gmail for example, once you enter your username and password their will be a small window opening on the left hand corner asking you if you want to save your password or something like that. Click save or remember password I think.

Some sites do not allow remembering passwords like paypal.
