Do many utilities / bills take online payment without first needing to be logged into the subscriber's account?

I don't have many, but those that I do have require that I log into my account first and then fill out the form to let me pay (and pay my own account, only).

There are some services in which I can pay cash, like Verizon mobile phone, but even then will they let just anyone pay? I did that once a couple years ago, on a kiosk, but I'm remembering that it asked me for my birthdate, or for the last digits of my SSN or something like that.
