What's the difference between Fast and Anonymous mode?

The default mode for NymVPN is the "Fast mode", which relies on a 2-server, tunnel-in-a-tunnel WireGuard setup. This mode is perfect for everyday privacy, quick browsing, streaming, and file sharing. It is actually using (on the client side) "AmneziaWG", a censorship-resistant version of WireGuard, which adds decoy packets before the handshake initiation. This obfuscates connection attempts, improving resistance to censorship while preserving the speed and reliability you rely on. You can learn more on the AmneziaWG page or its GitHub repository.

In the Anonymous mode, your traffic is routed through the 5-server Nym mixnet, going to an entry gateway, 3 "mixnodes", and an exit gateway before reaching the open internet. This option provides the maximum privacy. Note that this option introduces significant latency and speed reduction, and is best used for messaging, emailing or processing financial transactions.
