!!! warning ""

    QUIC, which is required by Hysteria2 is not included by default, see [Installation](./#installation).

!!! 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.
