Automatic user login when cart quantity refreshes

Hi Support,

I came across this issue when I update cart quantity and yet not logged in, the system automatically logs me in somehow remembering my login details which I used in the past.

How can I stop the auto login?

I am using free hikashop v1.5.0_2011-05-14 for J16.

Thank you!

The auto login is done by your browser which fills the username and password fields automatically.
If you don't save the password for your website on your browser, you won't have that.
