Authentication · Single Sign-On
One secure login for every application you run
We design, deploy and operate Keycloak SSO for your customer portals, internal tools and third-party SaaS — standards-based, fully owned by you, and built to survive real production traffic.
- OIDC, SAML 2.0 & OAuth 2.0
- Front- and back-channel logout
- Runs on upstream Keycloak 26.x
Standards & integrations
- OpenID Connect
- SAML 2.0
- OAuth 2.0
- PKCE
- Token Exchange
- LDAP / Active Directory
Overview
What single sign-on really means in production
SSO lets a user authenticate once and move between every connected application without signing in again. Getting there is less about flipping a switch and more about the details: consistent claims across apps, sane session lifetimes, logout that actually logs people out, and a cut-over plan that doesn't strand active sessions. That's the work we do.
What we deliver
- Realm and client architecture document
- OIDC and SAML clients configured as code (Terraform / OpenTofu)
- Protocol mappers and client scopes per application
- Single logout verified across all connected apps
- Integration snippets for your application stacks
- Runbook for onboarding new applications
Capabilities
What Single Sign-On covers
Configured, tested and documented on upstream Keycloak — then handed over or operated by us.
Every major protocol
Connect modern SPAs and mobile apps over OIDC with PKCE, and enterprise SaaS over SAML 2.0 — from one realm, with one user record.
Claims your apps expect
Client scopes and protocol mappers shape tokens and assertions per application, so each app gets the roles and attributes it needs and nothing more.
Logout that works
Front-channel and back-channel logout configured and tested end-to-end, so ending a session in one app ends it everywhere.
Multi-tenant ready
Keycloak Organizations give each B2B customer its own members, domains and identity providers without a realm per tenant.
Directory federation
Keep LDAP or Active Directory as the source of truth while Keycloak handles modern protocols in front of it.
Session policy by design
Idle and max lifetimes, remember-me and offline tokens tuned to your risk profile instead of left at defaults.
How it works
From first call to production
Map your application estate
We inventory every app, its protocol, how it consumes identity today and what it needs from a token — then agree the realm and client design.
Integrate and test
Clients, scopes and mappers are defined as code, wired into each app and tested for login, refresh, logout and failure paths in staging.
Cut over with a rollback plan
Apps move in waves with parallel running where needed, monitoring in place, and a documented rollback for every step.
Use cases
Where teams put it to work
Customer-facing SaaS
One account across your web app, mobile app and support portal, with enterprise customers bringing their own IdP.
Workforce & internal tools
Staff sign in once to dashboards, CI/CD, observability and admin tools, with access removed centrally when they leave.
Replacing a proprietary IdP
Move off Okta, Auth0 or Cognito to Keycloak you control, keeping user accounts and sessions intact through the migration.
FAQ
Single Sign-On questions, answered
Can Keycloak handle both SAML and OIDC applications at once?
Yes. A single realm can host OIDC and SAML clients side by side, and a user who signs in through one is recognised by the other within the same SSO session.
Do our applications need to change?
Usually only their authentication layer. Most frameworks have mature OIDC or SAML libraries; we provide the configuration and review the integration with your team.
What happens to users who are signed in during the cut-over?
We plan migrations in waves and, where needed, run the old and new identity providers in parallel so active users aren't forced out mid-session.
