!!! warning "Difference from official Hysteria2"

The official program supports an authentication method called **userpass**,
which essentially uses a combination of `<username>:<password>` as the actual password,
while sing-box does not provide this alias.
To use sing-box with the official program, you need to fill in that combination as the actual password.
