zeroauthy

Run zeroauthy — an Apache-2.0, clean-room identity provider you host yourself — from its published container image: generate the TLS material and master key it refuses to start without, bring it up on :8443, create the first admin, and pin, upgrade or roll back the image deliberately. Use when a person or a small organisation needs sign-in, OIDC, MFA or social and enterprise connections without renting an auth vendor.
