# Installation and getting started
This guide is intended for Windows, macOS, and Linux users because TrueConf client applications for desktops are cross-platform and have the same features and UI.
If you are just starting to get acquainted with video communication from TrueConf, it is recommended to familiarize yourself with brief instructions on how to start working with the application. Afterwards, you will be able to supplement your knowledge from this documentation as you work more actively with video communication.
# TrueConf desktop client application features
Please note that the features listed below are available when the application is connected to the most recent versions of TrueConf Server or TrueConf Enterprise. If you connect to older versions of the video conferencing server or to the TrueConf Online cloud service, some of the following features may not be available.

# Installing the application
Before installation, make sure that your computer and network connection meet our system requirements (these requirements depend on the expected video quality)
To get started with TrueConf client application, download it from the guest page of your TrueConf Server instance (please contact your server administrator to find out its URL address) or from our official website:
Before using the client application, make sure that your operating system and graphics card driver is up to date. Please note that we recommend downloading the drivers from the manufacturer's official website (Intel (opens new window), Nvidia (opens new window), AMD (opens new window)).
# Signing in
Depending on the settings of the video conferencing server to which you will connect and your location (e.g., the corporate network or the Internet), you may have to use one of the following authorization options:
When users connect to a corporate video conferencing server like TrueConf Server or TrueConf Enterprise, they can take advantage of multiple login, which allows them to sign in from multiple devices at the same time (e.g., a laptop and a smartphone).
If a user account is disabled on the side of TrueConf Server, the authorization will not be completed, and the corresponding message will be displayed. In case of such problems, please contact your server administrator.
# Authentication with the login and password.
To log in with your login and password, click the Sign in button:
Choose the login option in the pop-up window:
Corporate user account for authentication on the corporate server.
Cloud user account for authentication on the TrueConf Online cloud service without connecting to the corporate server.
Here, we will discuss authentication with the Corporate user account.
Enter your corporate email or TrueConf ID (login). Click the Next button so that the application could try to automatically detect the server and connect to it.
If you choose to sign in to the cloud service, after entering your email or TrueConf ID, you will need to check your mail box for the authentication code.
If the application cannot automatically connect to the selected server, you will be asked to double-check your email or enter the server address manually. Click the button Enter server address manually which will open the menu where you can enter the address in the corresponding field or select one of the detected servers. The list of detected servers will also include the servers you previously connected to:
Choose the required server from the list or enter its address in the field, then click Connect.
# SSO authorization
SSO (Single Sign-On) is a technology that allows a user to sign in to multiple applications or web services with the same login information.
In this case it will enable users to sign in to TrueConf client application without entering the login and password if they have already signed in to the operating system. However, two requirements have to be met:
You will need to be authorized in the OS with the domain account (specified on the LDAP server).
TrueConf Server to which you are connected should be integrated with the LDAP server from part 1.
This feature is available not only on Windows (where Active Directory is used as the directory service), but also on Linux.
If these conditions are met, you will be automatically signed in to TrueConf application once it is started.
# Two-factor authentication via AD FS, Keycloak, etc.
Click the Sign in button on the home page of the application:
Click the Corporate user account button:
Next, either enter the server address manually, as we showed earlier, or the application will automatically connect to the required server, if this feature is enabled by the administrator.
Click the
button to authenticate via AD FS.
The AD FS authorization window will be displayed on the screen. Type your domain login and password (contact the server administrator to receive them). Next, click Sign in.
Once you have signed in, your user account information will be displayed in TrueConf client application.
In addition to AD FS, your company may use another provider for implementing two-factor authentication, such as Keycloak.
The general application login scheme described for AD FS will remain the same when using another provider.
# Offline mode
You will be able to sign in and use some of the application features in offline mode.
If connection with the server is lost and you have signed into the client application before, you can still use some application features in offline mode. For example, you can view the history of received messages or write a message that will be sent as soon as connection is restored. In offline mode, you will be unable to make calls, exchange messages, and upload or download files.
When connection to the server is restored, you will be able to continue working in online mode.
# Multi-login
You will be able to sign on multiple devices with the same account. In this case:
When using the application on multiple devices, you won't have to sign out from your profile on the second device
Make calls/participate in different conferences from different devices at the same time
Reconnection to calls will be available simultaneously on all devices.
Multiple login is supported on all platforms, including mobile devices (iOS, iPadOS, Android), PCs running Windows, macOS, and Linux, smart TVs (Android TV), and browsers.
# Joining a conference as a guest
When the application is run for the first time, you will see a window offering you a choice between two buttons: Sign in or Join conference.
You can join a public conference (webinar) without authenticating on the video conferencing server. To do it, click the Join conference button and enter your name, which will be displayed in the participant list:
In this window, you can also choose:
Your microphone
Audio output device (headphones or speakers)
Video camera.
More advanced application settings are available after clicking the 
button. For more information about the Settings menu, refer to the corresponding part in this documentation.
# Exiting the application
By default, 
(exit button) minimizes the application to tray. You also can change this button action in Settings → Preferences → General. To exit the application, you need to:
Right-click on the application icon in the system tray (bottom right corner of the desktop).
Select Exit.
