Getting Started

Creating Your Nexus ID

Your Nexus ID is your universal identity across the entire CDA ecosystem. One account, every app, every service.

How to create your Nexus ID: 1. Visit cda.nexus or click "Sign In" on any CDA property 2. Choose an OAuth provider: Google, GitHub, Microsoft, or LinkedIn 3. CDA uses Empty Fortress authentication. There are no passwords. Ever. Your identity is verified through your OAuth provider. 4. After first sign-in, you receive a Nexus ID and can set your callsign

What you get with a Nexus ID: - C3 Command Post access (your security dashboard) - Arena profile with XP tracking - The Shield (your certification visualization) - Charlie Recon scan history - Access to CDA.Wiki, CDA.Theater, and CDA.Institute - Community forum access - Waitlist eligibility for upcoming features

Your Nexus ID starts at the "Civilian" membership tier (free). From there you can upgrade to Cadet, Enlisted, or Officer to unlock additional features and mission access.

Privacy: CDA never stores passwords. We never share your personal data with third parties. Your identity data is encrypted at rest and protected by row-level security policies.
