J PROJECT PLATFORM uses essential cookies to keep sessions secure, remember language and theme choices, protect forms and complete one-account sign-in between approved Project subdomains.
Essential cookies
Authentication, session security, CSRF protection, SSO state and owner impersonation safety depend on essential cookies. These cannot be disabled while using protected Projects.
Preferences
Language is stored in the secure session and your J Account. Theme preference is stored only in your browser.
Isolated authentication sessions
Every protected subdomain keeps its own host-only authentication session. One-time authorization codes connect it to My Account. A separate signed indicator may be shared across approved Platform subdomains only to show the correct signed-in navigation; it cannot authenticate a protected request.
