You can disable automatic autofill in preferences and only manually insert the login/password on sites that you want. This way you will not be asked for password until you really want to autofill saved credentials.
QupZilla 2.2.5 on openSUSE Tumbleweed 20180213
When using the built-in master password-encrypted password backend, QupZilla asks for the master password on sites with a saved login.
If you cancel this dialog because you don't want to log in to a site at the moment, you have to hit "Cancel" twice before it goes away. It should probably disappear after the first time.
