Keycloak
Open-source identity and access management for staff and member apps
oss-osi-approved full guide featuredOverview
Keycloak provides SSO, identity brokering, and user federation. Technical operators use it to centralize login for internal tools (helpdesk, wiki, booking) and reduce password sprawl across the coworking stack.

Cost reality
Software is free; cost is infrastructure, HA design, and operator skill.
Self-host notes: Production typically needs Postgres, reverse proxy TLS, and backup of realm exports.
Pricing and free-tier limits change frequently; re-check official pricing before budget decisions.
Tasks reduced or augmented
Software does not replace community or ops staff. It may reduce or augment:
- Reducing duplicate user accounts across internal tools
- Standardizing joiners/leavers access changes
- Enabling SSO for staff applications
Human oversight still needed
- Realm and client configuration reviews
- MFA policy decisions
- Break-glass admin procedures

Risks
| Area | Notes |
|---|---|
| Vendor lock-in | Evaluate export formats and API completeness before deep customization. |
| Security | Apply updates promptly; restrict admin access; enable TLS. |
| Compliance | Operator remains responsible for privacy and local regulatory obligations. |
| Licensing | Confirm license fits commercial coworking use. |
| Operational | Plan backups, monitoring, and a restore drill before production use. |
Coworking fit
Roles: technical-operator, operations-manager, multi-location-operator
Workflows: member-onboarding, member-offboarding, access-provisioning, compliance-review
Problems: secure-door-access, integrate-stack, privacy-compliance, multi-location-consistency
Smallest useful experiment
Stand up Keycloak with one realm, connect a single staging app via OIDC, and practice disabling a test user.
Typical time to first value: 1–3 days
