WireGuard for Android (official)

You can configure the official WireGuard Android app by importing a `.conf` file provided by your VPN provider or by scanning a QR code. The app uses public and private cryptographic keys to establish a secure connection, bypassing the need for traditional username and password logins. This makes setup highly secure and fast compared to older protocols like OpenVPN.

Yes, the official WireGuard app on Android includes a feature for split tunneling through its "Applications" setting. You can check or uncheck specific apps installed on your phone so that only their traffic is routed through the VPN tunnel. This allows you to keep your banking or local apps on your regular connection while routing browsing traffic through WireGuard.

WireGuard utilizes state-of-the-art cryptography, specifically ChaCha20 for symmetric encryption and Poly1305 for message authentication. It also employs Curve25519 for key exchange and BLAKE2s for hashing. These modern protocols result in a much smaller codebase and lower latency compared to older VPN standards.

Yes, the official WireGuard app is entirely free and open-source software available on the Google Play Store. The source code is publicly hosted on GitHub and managed by the core WireGuard development team. Users and security researchers are free to audit the code or compile the application themselves.
