How it works

What is WireGuard, and why is it quick?

WireGuard is a newer VPN protocol, designed to be much simpler than the ones before it. Less code means less to go wrong, and less work for your phone on every packet it sends.

Connecting takes one short exchange. Your phone says hello, the server replies, and the encrypted tunnel is up. After that, WireGuard quietly swaps in fresh keys every couple of minutes.

Tunnexa then checks that the server really answered. If replies stop, the app tells you, rather than showing Connected over a link that’s gone quiet.

No reply within 20 seconds? Tunnexa disconnects and says it couldn't reach the server, instead of leaving you on a dead link.

Security

Is WireGuard secure?

Yes. It's built on modern encryption, and its design leaves very little room for mistakes.

01

One fixed set of encryption

There are no cipher settings to choose, so nobody can pick a weak one by accident.

02

Small enough to check

WireGuard's code is far smaller than older VPN protocols, which makes it easier for security researchers to review.

03

Keys that keep changing

Every fresh handshake brings new keys, so an old key can't read newer traffic.

04 Honest limit

What it doesn't do

WireGuard doesn't hide that it's a VPN, so networks that block VPNs can recognize it. That's exactly what AmneziaWG, a disguised WireGuard, is for.

WireGuard vs OpenVPN

Both encrypt everything you send. They differ in how they get it there, and where they struggle.

WireGuard and OpenVPN compared

Design Newer, small and simple Older, flexible and very widely used
On your phone Quick to connect, and quick to recover when you switch networks Steady, a little slower to connect
Travels over UDP UDP or TCP
Strict Wi-Fi Often blocked The TCP version gets through more often

FAQ

WireGuard questions

Something not covered here? Write to us at support@tunnexa.com.

What is WireGuard?

WireGuard is a modern VPN protocol that builds an encrypted tunnel between your device and a VPN server. It's known for being lean and quick, and it's the quickest option in Tunnexa.

Is WireGuard secure?

Yes. It uses one fixed set of modern encryption and refreshes its keys every couple of minutes. It doesn't hide that it's a VPN, though, so on networks that block VPNs, use AmneziaWG.

Is there a free WireGuard VPN for Android?

Tunnexa is free and offers WireGuard to everyone, guests included. Install the app, tap Skip, and connect.

Is WireGuard faster than OpenVPN?

On most networks, yes. It's leaner and connects quicker. On strict Wi-Fi, though, OpenVPN TCP may connect where WireGuard can't.

Why won't WireGuard connect on some Wi-Fi?

Some networks drop the kind of traffic WireGuard uses, and some spot VPNs and block them on purpose. Try OpenVPN TCP on strict Wi-Fi, and AmneziaWG where VPNs are banned.

Do I need the WireGuard app to use it?

No. WireGuard is built into Tunnexa, so there's nothing else to install and no config file to import.
