SSO (Google, Microsoft, GitHub) is available on all tiers. Custom OIDC provider support is even available in our ~MIT~ (Apache2) licensed community edition if you self host Distr. Even TOTP MFA is available for all users and part of the community edition.

How can we improve in reducing SSO tax?

Starter package does not show SSO as being available. Thanks for clarifying https://distr.sh/pricing/

I see Apache 2 licensed code in your GitHub but not MIT. Is there another repo or that's what you were referring to?

Custom SSO integrations often require specific development and are therefore not available in our beginner tier.

Oh my bad. Our repository[1] is obviously Apache2.0 licensed, not MIT. Thanks for pointing that out.
