Your free account
unlocks everything.
One sign-up gives you instant access to 11 products — productivity, study resources, collaboration, civic engagement, and more. No credit card. No catch.
One account opens every door.
When you create a Centauri account, you immediately get access to the entire ecosystem — no upgrade, no waiting list, no "premium" tiers for basic features.
Universal SSO
Log in once and you're authenticated across all 11 products. JWT-based sessions on .gocentauri.com mean no more re-entering passwords.
Google Sign-In
Already have a Google account? One click and you're in. Full OAuth 2.0 integration — no new password to remember.
Instant Access
No verification queues. As soon as you confirm your email, every product is unlocked — Productivity, Resources, Workplace, Counted, and more.
Centralized Settings
Theme, accessibility, privacy, notifications, and billing — all controlled from one place at settings.gocentauri.com.
Data Portability
Your data is yours. Export everything — tasks, calendar, settings — anytime. Import from other tools when you switch over.
Bot Protection
Cloudflare Turnstile guards your account — no annoying "click every traffic light" puzzles. Smart, invisible protection.
Three steps. Thirty seconds.
Sign up with email or Google
Head to accounts.gocentauri.com and enter your email + password, or click "Continue with Google" for instant creation. That's it.
Confirm your email
Check your inbox for a verification link. Click it and your account is fully activated. This step keeps your account secure and enables password recovery.
Start using any product
Once verified, visit any Centauri product — Productivity, Resources, Workplace, Counted, or any other. You'll be automatically signed in everywhere. Use the 9-dot menu in the top right of any page to switch between tools instantly.
Your account is locked down.
We take security seriously — not as a marketing checkbox, but as a core architecture decision.
JWT Session Tokens
Industry-standard JSON Web Tokens with short expiry and secure, HttpOnly cookies. Sessions can't be hijacked via JavaScript injection.
Domain-Level SSO
Cookies are set on .gocentauri.com, so they work across every subdomain without sharing credentials through URLs or local storage.
Google OAuth 2.0
We never see your Google password. OAuth tokens are scoped to minimum permissions — just email and profile.
Cloudflare Turnstile
Signup and login are protected by invisible bot detection. No CAPTCHAs, no frustration — just smart security at the edge.
Email Verification
Every account is email-verified before full activation. This prevents spam accounts and enables secure password reset flows.
2FA Coming Soon
TOTP-based two-factor authentication with backup codes is on the roadmap — because security should be a feature, not an afterthought.
