!!! warning "Difference from official Hysteria2"

The official Hysteria2 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.
If you are planning to use sing-box with the official program,
please note that you will need to fill the combination as the password.
