Prerequisites and Requirements

Before installing Orion Authenticator, ensure the target workstation meets the requirements below

---

Supported operating systems

macOS

• macOS 13 (Ventura) or later

• 350 MB of available disk space

Windows

• Windows 10

• Windows 11

• Windows Server 2016

• Windows Server 2019

• Windows Server 2022

Network requirements

Orion runs a local HTTPS server to communicate securely with the 1Kosmos login page in the browser. One of the following ports must be available on the workstation:

Port range	Purpose
47061–47069	Local HTTPS server (loopback)

These are loopback ports only — Orion does not open any inbound ports to the network. The HTTPS server is bound to localhost.

Windows prerequisites

The following runtime libraries are required on Windows. The Orion installer attempts to download and install these automatically, but they can also be installed manually if your organization restricts installers from downloading third-party libraries.

Runtime	Version	Download (x86)	Download (x64)
Microsoft Visual C++ Redistributable	2015–2022	x86	x64
ASP.NET Core Runtime	8.0 or later	x86	x64
.NET Desktop Runtime	8.0 or later	x86	x64

Supported browsers

Orion supports account onboarding from the following browsers:

• Google Chrome

• Microsoft Edge

• Mozilla Firefox

• Safari (macOS only)

• Brave

Brave users — Disable Shields when onboarding accounts. Brave's privacy protections block certain cross-origin requests required for the browser to detect Orion on the workstation.

Permissions

Orion requires the following permissions to function:

• Local HTTPS certificate trust — Orion installs a certificate into the workstation's trust store to enable secure communication between the local HTTPS server and the browser

• File system access — Read and write to the installation directory for log files and account data

• Network access — Outbound HTTPS to the 1Kosmos platform
