Don't store the encfs password, require explicit mounting

I use encfs to encrypt some data in my dropbox directory. Everything works well. For simplicity let's assume that i have created the directories ~/encrypted and ~/decrypted. Every time I log in into my linux account ~/decrypted will automatically be mounted. Is there a way to avoid this and force the user (me in my case) to enter the password before ~/decrypted can be mounted? I use Linux Mint 17.3 with Cinnamon. I imagined that my encrypted folder is unmounted all the time except when want to access it. Then a little dialog could appear where I have to enter my password.
