In today’s security-conscious environment, authentication isn’t just a technical requirement—it’s a core component of maintaining system integrity and trust. For the FusionReactor community, where reliability and control are paramount, our latest update brings meaningful improvements designed with you in mind.
We’re pleased to announce a major upgrade to FusionReactor’s authentication system. This release delivers significant enhancements to both security and usability, reinforcing our commitment to robust, developer-focused tooling.
What’s New in FusionReactor Authentication?
You’ve relied on FusionReactor to monitor and maintain mission-critical applications. With this update, we’ve modernized how you access your account while keeping simplicity and security front and center.
1. Passwordless Authentication with Passkeys
Say goodbye to password fatigue. Passkeys represent a more secure, phishing-resistant way to log in—no passwords required. Instead, log in using device-based authentication like biometrics or a hardware key.
- Phishing-Resistant: Passkeys can’t be tricked by fake login pages.
- Developer-Friendly: They simplify security management across teams without compromising control.
Whether you’re managing production apps or jumping between dev environments, Passkeys offer a streamlined, secure login flow that just works.
2. Smarter Access with Existing Google Login
FusionReactor has long supported signing in with your Google account, providing a secure and convenient alternative to traditional username/password login. While this release doesn’t add new social login providers just yet, we’ve laid the groundwork for future expansion. In the meantime, Google login remains a reliable option – especially for teams already using Google Workspace.
3. Built-in Multi-Factor Authentication (MFA)
Secure authentication requires more than just a strong password (or even a Passkey). FusionReactor now includes built-in support for MFA/2FA:
- Time-based one-time passwords (TOTP)
- Authenticator apps
- Biometric-based verification
We strongly recommend enabling MFA—especially for production environments or administrative accounts.
4. Improved Multi-Tenant Support
Many developers and consultants work across multiple projects and organizations. With this update:
- Switch accounts without logging out.
- Manage multiple tenants seamlessly under a single session.
- Reduce context-switching friction between environments.
This is especially useful for managed service providers, agency developers, and enterprise teams that work with multiple clients.
Switching Organizations
If you’re a member of multiple organizations, you can easily switch between them using the account menu:
Multi-Tenancy
FusionReactor supports multi-tenancy, allowing users to access multiple organizations from a single login, without needing to use separate email aliases (e.g., +infra).
How it Works
This means:
- You no longer need to create multiple accounts with +aliases in your email.
- You can use one primary email address to access all linked organizations.
- All associated orgs appear in the “Switch Organization” menu, accessible via the bottom-left account dropdown.
Important Note
To take advantage of this setup:
- You must use an actual email address (not a one-time or unauthenticated session).
- If you’re not logged in with a recognized email, you’ll only see the organization tied to that specific session.
✅ Once invited to multiple orgs with the same email, you can seamlessly switch between them — no need to reauthenticate or re-register.
Why This Upgrade Matters
- Security, Upgraded: Passkeys and MFA work together to provide a defense-in-depth approach.
- Flexibility: Choose the login method that fits your workflow—whether you prefer local authentication, SSO, or biometrics.
- Operational Efficiency: Faster logins and better account management free up time for actual development and observability.
This isn’t just a security update. It’s an infrastructure improvement that honors your time, secures your data, and streamlines your workflow.
FusionReactor remains committed to delivering practical, secure tools that fit the way developers work.
