Qt Network Authorization

Qt Network Authorization provides a set of APIs that enable Qt applications to obtain limited access to online accounts and HTTP services without exposing users' passwords.

Currently, the supported authorization protocol is OAuth, versions 1 and 2.

Using the Module

Using a Qt module requires linking against the module library, either directly or through other dependencies. Several build tools have dedicated support for this, including CMake and qmake.

Building with CMake

Use the find_package() command to locate the needed module components in the Qt6 package:

find_package(Qt6 REQUIRED COMPONENTS NetworkAuth)
target_link_libraries(mytarget PRIVATE Qt6::NetworkAuth)

See also the Build with CMake overview.

Building with qmake

To configure the module for building with qmake, add the module as a value of the QT variable in the project's .pro file:

QT += networkauth

Overview

The goal of this module is to provide a way to handle different authentication methods present on the Internet.

There are several authentication systems, including:

• OAuth 1
• OAuth 2
• OpenID
• OpenID Connect

These systems allow the application developers to create applications which use external authentication servers provided by an Authorization Server. Users of these services need not worry about passing their credentials to suspicious applications. Instead, the credentials are entered in a known and trusted web interface.
