How do I create a roaming client configuration?

From the Tunnels tab, click Add and specify a description. As long as the Remote Endpoint Type is Roaming and the Remote Per IP Address is populated, you can click Done, click Save, and then click the Remote Client icon to generate a QR Code/Configuration file for your roaming client.

How resilient is a WireGuard connection?

WireGuard is built for roaming. If your device changes networks, e.g. from WiFi to a mobile/cellular, the connection will persist because as long as the client sends correctly authenticated data to the WireGuard VPN server, the server keeps the connection alive.

What cryptography is used in WireGuard?

ChaCha20 for symmetric encryption, authenticated with Poly1305, using RFC7539's AEAD construction Curve25519 for ECDH BLAKE2s for hashing and keyed hashing, as described in RFC7693 SipHash24 for hashtable keys HKDF for key derivation, as described in RFC5869 Noise_IK handshake from Noise, building on the work of CurveCP, NaCL, KEA+, SIGMA, FHMQV, and HOMQV All packets are sent over UDP
