bVNC: Secure VNC Viewer

Control your Windows, Mac, Linux, or BSD computers remotely using a secure VNC viewer that works from anywhere without complicated network setup. bVNC: Secure VNC Viewer is an open-source remote desktop client built for users who demand both accessibility and encryption-grade security on their Android devices.

Connect to your machines with military-strength encryption using SSH tunneling, VeNCrypt with x509 certificates, or AnonTLS protocols. These security methods prevent man-in-the-middle attacks and deliver superior encryption compared to standard RDP connections. The app supports public/private SSH key authentication, letting you import encrypted or unencrypted RSA keys in PEM format for seamless, password-free connections.

Navigate your remote desktop with full multi-touch control. Single-finger taps perform left-clicks, two-finger taps execute right-clicks, and three-finger taps trigger middle-clicks. Drag with any button combination, scroll smoothly with two-finger drags, and pinch-zoom to inspect details on your screen. The app delivers full mouse support with hardware keyboard compatibility, so you control your computer exactly as you would in person.

Optimize your viewing experience with multiple scaling modes: zoom freely, fit your entire desktop to the screen, or view at actual pixel size. Force landscape orientation, activate immersive mode to maximize screen real estate, or keep your screen awake during long sessions. Dynamic resolution changes let you reconfigure your desktop while connected and even control virtual machines from BIOS through operating system startup.

Choose from four input modes tailored to how you work: two direct touch modes, a simulated touchpad, or single-handed input for one-handed operation. In single-handed mode, long-tap to select from clicks, drag modes, scrolling, and zooming—perfect for tablets or when your other hand is busy. Stowable on-screen keys keep your workspace clean while remaining instantly accessible.

The app works with virtually all VNC servers including TightVNC, UltraVNC, TigerVNC, RealVNC, and Mac OS X's built-in remote desktop. It's fully compatible with PiKVM and supports AutoX session discovery for streamlined connections. Tight and CopyRect encodings accelerate updates over slower connections, while color depth reduction optimizes performance on bandwidth-limited networks.

Copy and paste between your Android device and remote computer seamlessly. Capture Samsung DeX, Alt-Tab, Start Button, and Ctrl+Space. Toggle view-only mode when you need to observe without controlling. Built-in help covers connection setup, usage tips, and input techniques.

Upgrade to bVNC Pro for master password protection and multi-factor SSH authentication. Whether you're supporting a family member's computer, accessing your work desktop from the road, or managing multiple machines, bVNC: Secure VNC Viewer delivers the control and security you need.
