My VPN-provider Integrity VPN rolled out their support for Wireguard the other day. I just installed the Wireguard-client on my phone and it was ridiculously easy to setup. I imported a text file and I could then instantly connect.
@nesc There's no settings, it just works. If you have the kernel module for it there's no impact on performance and battery life. Not that either seems to be an issue when running it in the user space on my 4 year old phone, so far.
