Single-sign-on is a large and painful feature to develop, that most people don't need, and that the companies that need it are willing to pay for. It's the perfect candidate for a higher-tier pricing structure. This makes much more sense than tiering on a feature that everyone needs.

Sso should be the default really. And as a starting point every language has openid connect implemented. Yes it needs work but surely better than the average password reuse?

For large and small companies surely the best way to maintain their users

SSO in 2017? Sure. In 2024? No way.
