SSO doesn't add security, it enables bulk management of accounts. Which only affects security in an indirect way.

Technically it doesn't add security, but I think the recommendation for SSO stems from the reality that peoples behavior gets worse if they have to maintain more accounts. And if they use the same password, the least secure system affects the others in a classical setup.
