Identity provider / Built by Combine
Your applications belong together. Give people one account to move between them, and give your team one place to manage access.
Sign in once. Keep moving.
Single sign-on across your applications.
A space of your own.
Your users, your providers, your rules.
Standards at the core.
OpenID Connect and OAuth 2.1.
01 / How it works
Authentication should get people where they’re going. Citadel brings your applications into a shared space, so the next sign-in is one they can skip.
Give an organisation or application group its own identity home, on its own subdomain or a verified domain you bring.
Choose your sign-in methods, connect your identity providers, and register applications using OpenID Connect.
People sign in once and move between connected applications. Their profile, security settings and active sessions have one home.
02 / The platform
A considered foundation for the people who use your apps and the teams who build them.
Each space keeps its own users, sessions, providers and applications. Clear boundaries for your organisations, with a consistent way to manage them.
acme.example.com
One account. Every app here.
studio.example.com
One account. Every app here.
Passwords, magic links, email codes or a provider people already know. Choose what fits each application.
A login that feels like your product. Choose a design, make it yours, and preview it before it goes live. Customise by space or application.
Add a second factor with authenticator and recovery codes. Keep provider credentials encrypted at rest and give people control of their sessions.
More than a password.
Manage users, applications, domains and connections in one console. People get their own account area for profiles, security and access.
The right tools for each role.
03 / For developers
Use the OpenID Connect client you already know. Citadel handles identity; your application gets back to doing what makes it useful.
// Your space. Your issuer.
issuer = "https://auth.example.com"
One integration. All your sign-in methods.
Example endpoints for a space using a custom domain.
04 / A little clarity
