Reasonable, WireGuard is just way better.
DAITA, Multihop, and Quantum-resistant tunnels are also all WireGuard exclusive features. I imagine the majority of users haven’t used OpenVPN in a long time.
Yeah i agree that most of us would be using wireguard by now due to its speed benefits.
But since openvpn has been battle tested for long time , an option to use openvpn on limited servers, wouldn’t hurt. (apart from the company having to spend on its maintenance)
people with old routers would still like it i guess.
Still Jan 2026 is a long time to wrap our heads around one protocol
Doesn’t using OpenVPN with Mullvad offer flexibility in how the 5 device limit is applied? I don’t do this so I might be wrong/out of date, but I did look into it when I first signed up. ISTR you are limited to 5 devices active at one time with OpenVPN, whereas you can only have 5 WireGuard keys set up at once.
I have some devices which I rarely use, and never use simultaneously, and in theory using OpenVPN would have allowed me to set all these up with Mullvad VPN service without needing to switch Wireguard keys around.
I appreciate there are some complications around enforcing a limit on the number of devices without doing excessive logging of user activity, but it is a bit of a shame if this change removes one easy-ish way to share the VPN among multiple devices.
Quantum resistance: OpenVPN also supports PSKs (pre-shared keys) just like WireGuard.
Multihop: Nothing about OpenVPN that it can’t multihop.
DAITA: OpenVPN is based on TLS, so I’m unsure it needs packet flooders like DAITA. May be it does. In my experience implementing anti-censorship measures, WireGuard definitely does.
My point was that all those features are WireGuard exclusive in Mullvad VPN, which has given users a lot of reasons to switch to using WireGuard beyond the speed benefits. I understand they could be implemented with OpenVPN if desired.
MullvadVPN already implements Wireguard over TCP and IPv6 so it seems unlikely that the loss of OpenVPN will be an immediate inconvenience
In MullvadVPN, is there still anything left that OpenVPN can do that Wireguard cannot?
This make sense : on Desktop, Wireguard now has gained advanced censorship-resistance, something which was previously only available on OpenVPN.
On Mobile, they are working on bridging the feature gap with multi-hop/DAITA. When this is done, Mullvad will pretty much have feature parity, and this seem a good time to stop caring about OVPN since it adds additional complexity.
so it seems unlikely that the loss of OpenVPN will be an immediate inconvenience
In MullvadVPN, is there still anything left that OpenVPN can do that Wireguard cannot?
There is one thing that is pretty major if it impacts you and not important if it doesn’t impact you. That is what @SteveR highlighted earlier (that the device limit is much more rigid and less flexible with Wireguard compared to OpenVPN):
