Auth0 organisations self service signup
Friday, June 19, 2026
Auth0 is a SaaS identity provider that lets you add production-grade authentication to your product quickly. It offers two main flavours: Business-to-Consumer (B2C) and Business-to-Business (B2B). Today, we’re focusing on the B2B use case. Auth0 B2B revolves around Organizations: a model you can use to represent your own tenants, companies, or organisations. You can map users to one or more organisations, assign them different roles inside each one, and enable SSO connections, complete with domain discovery, on a per-organisation basis.
