As it's coming up to Black Friday/Cyber Monday I was hoping to add a couple of years' ProtonVPN to my little collection of trusted VPN services.Unfortunately no WireGuard is a killer for me, as it's so much lighter, faster and easier to use cross-platform compared to IPSEC or the old, bloated single-threaded openvpn. I added my votes but I guess I'll be waiting a year to check back with you again. I know from Reddit that Jason Donenfeld himself (WireGuard 'inventor' and chief coder) has offered to help with your implementation, as he did for Mullvad and AzireVPN, both of whom now run it commercially, successfully. I know you cited authentication difficulties but when the guy who literally invented the thing offers his help...?

WireGuard has been formally verified differently to openVPN https://www.wireguard.com/formal-verification/
Moreover, WireGuard is made of about 4k LOC while openVPN about 120k LOC https://www.wireguard.com/presentations/

WireGuard has a great future ahead.But intil it is finished and audited is not really safe.So it's best to stick with OpenVPN which is both finished and audited.The only alternative,which is not as safe as OpenVPN is IKEv2/IPSec.

Yes, it would be a great idea to offer Wireguard.

Instead of being good little sheep and following the herd, you could be leaders and pioneers in a VPN revolution.

P.S.: I use Wireguard for free, offered by AzireVPN.

This would be incredible, I use WireGuard myself with Mullvad and I'm a long time customer of their service but it would be nice to see ProtonVPN adopt this as well.

Wireguard is the future of VPN protocols
Open sourced, best cryptographic cyphers, only 4.000 lines of code and faster than other protocols.
quote from the Wireguard website:
"WireGuard® is an extremely simple yet fast and modern VPN that utilizes state-of-the-art cryptography. It aims to be faster, simpler, leaner, and more useful than IPSec, while avoiding the massive headache. It intends to be considerably more performant than OpenVPN. WireGuard is designed as a general purpose VPN for running on embedded interfaces and super computers alike, fit for many different circumstances. Initially released for the Linux kernel, it is now cross-platform and widely deployable. It is currently under heavy development, but already it might be regarded as the most secure, easiest to use, and simplest VPN solution in the industry."

their is many vpn tool out their, it would be cool if they supported them, but the many question is how secure are they.

I'm not familiar with the protocol. But I can say that the OpenVPN app does tend to use quite a bit of battery power to maintain an active connection.

The protocol is the best in term of security and auditability about 4k lines of code compared to OpenVPN that consists of around 120k lines of code.
Moreover, the protocol is the best in term of speed and battery usage since it is multithread with support to SSSE3, AVX, AVX2, AVX512, and NEON-accelerated implementations of its ciphers.
Finally, the protocol is good for mobile phones because since it was developed as a “stealth VPN,” by default not sending any packets unless there is actual data to be sent. This has the effect of not draining the battery like other VPN clients commonly do.
