How is single sign on (SSO) more secure than having several logins when it’s basically using the same password for everything?

The theory is that heavily securing the SSO system is far more effective and efficient than trying to heavily secure each other system independently. Would you rather trust a specialized SSO company to secure their stuff or trust all tens or hundreds of sites you may login to, ran by admins of varying capabilities? Not to mention having a single really good and long password you can remember is far superior to having many different weak, or even strong, passwords you'll have to put down somewhere. Of course in a personal environment SSO is in a bit of competition with password managers, which don't require the same level of trust of a third party entity (especially if it's an open source password manager).
