MacBook doesn't ask for password anymore

[asdfgbg]

Hello all
I have a little problem, since today my MacBook Pro Retina with Mavericks doesn't ask for the admin password anymore when I install programs like Chrome etc.
The strange thing is yesterday it has asked for the password and I didn't change anything in the security preferences.

Some things don't need a password.
