Safer sign-in and security tools for the systems you run.

SSH, desktop and VPN approvals
Companion tools add phone approval to supported SSH and computer sign-in flows. Windows packages include the approval service, a local HTTPS admin page, and setup guides.
The Ubuntu OpenVPN integration checks a separate client certificate and then requests a time-limited Thessley QR approval for every connection and reconnect.
For Ubuntu 24.04, install the signed Linux package from the APT repository hosted on the Orange Pi 5, or download the source archive. Windows packages are also available, with installation guidance and checksums.
