It's below the fold on rosenpass.eu but:

> Rosenpass is a key-exchange protocol using techniques that are secure against attacks from quantum computers. It achieves the same security guarantees as WireGuard, using two strong post-quantum key exchange methods – Classic McEliece and Kyber.

> To use Rosenpass, you don't have to get rid of WireGuard; Rosenpass handles post-quantum security, WireGuard handles pre-quantum security and high-speed data transmission.
