TeamViewer Host is the module installed on a computer to make it permanently reachable for unattended remote access. It runs as a service, so administrators and colleagues can connect without anyone being present to approve the session.
TeamViewer Host is the module that turns a computer into a permanently accessible device: it installs as a service, starts with the system, and waits for incoming connections rather than requiring someone at the far end to read out a session code. Devices are assigned to an account, so authorised users see them in their list and connect whenever the work needs doing, including before a user logs in. That makes the module suitable for office workstations, servers, kiosks, laboratory instruments, and point-of-sale terminals that must be reachable for maintenance. Connections support remote control, file transfer, chat, printing, and multiple monitors, and sessions can be recorded for the record.
TeamViewer Host differs from on-demand support tools in one important way: it is designed to stay installed and managed. Administrators deploy it in bulk, assign devices to accounts or groups, and control who may connect through permission policies, so a vendor or contractor can be given access to specific machines rather than the whole estate. Because the service starts with the operating system, a machine that has not been logged into since a restart is still reachable, which matters for servers and for users who report faults before signing in. Wake-on-LAN and remote reboot extend that further. Where a technician would otherwise open a client such as RealVNC Viewer to an address, here the device is simply present in a list of assigned computers.
TeamViewer Host earns its keep on machines that must be reachable on someone else's schedule. Because no one has to be sitting in front of the computer, updates can be applied at night, a stuck terminal can be restarted before opening hours, and a diagnostic check can run without interrupting a colleague's afternoon. Device assignment means access follows a person's role rather than a shared password, and removing someone from an account removes their access to every machine at once, which is far easier to audit than a list of local credentials. Remote control, file transfer, printing, multi-monitor support, and session recording cover the routine work, while wake-on-LAN and remote reboot handle the cases where the machine is asleep or unresponsive. For a fleet of kiosks, instruments, or workstations, the result is fewer site visits and faster fixes.
Key capabilities and highlights.
TeamViewer Host installs as a service that starts with the operating system, so the computer answers connection attempts even when nobody has signed in. Restarting the machine does not remove access, which suits servers and shared workstations.
Devices are tied to an account or group instead of a shared password, so authorised users see exactly the computers they may reach. When someone leaves a team, removing their account access instantly closes the door on every assigned device.
Technicians can view the screen, take control of keyboard and mouse, work across multiple monitors, and switch between displays during a session. That makes troubleshooting a stalled application or a misconfigured setting possible without a site visit.
A sleeping computer can be woken on the local network, and a machine that is running but unresponsive can be restarted remotely and reconnected once it returns. Maintenance windows therefore do not depend on someone being in the building.
Files move between the technician's machine and the device through a transfer panel, documents can be printed to a local printer, and chat keeps both sides informed. TeamViewer Host covers these needs without leaving the session.
Sessions can be recorded and connection activity logged, giving administrators a complete record of who reached which machine, when the connection started, and how long it lasted. That supports compliance reviews and helps resolve disagreements about how a fault was handled.
Access can be restricted by account permissions, trusted devices, and optional two-factor authentication, while sessions can be configured to display a black screen during sensitive work so onlookers see nothing. Encryption protects the traffic passing between the two machines.
TeamViewer Host can be rolled out across many computers in bulk, and administrators manage assignments, groups, and policies centrally rather than configuring each machine by hand. That keeps a growing estate consistent as devices are added or retired.

Common questions about TeamViewer Host.
It provides unattended remote access to computers that need to be reachable at any time, such as servers, office workstations, kiosks, and laboratory instruments. Administrators assign the device to an account, and authorised users connect whenever work needs to be done.
QuickSupport is launched by the person receiving help and produces a one-time session code, which suits ad-hoc support. TeamViewer Host stays installed as a service so connections need no action at the far end, which suits machines that are managed on a schedule.
No. Because the module runs as a service from system start, a technician can connect whether or not a user is signed in. Access is controlled by account permissions assigned in advance rather than by an approval at the machine.
Wake-on-LAN can start a machine on the same local network, and a running but unresponsive computer can be restarted remotely, with the connection re-established once it comes back. That keeps maintenance possible outside working hours.
Technicians can control the desktop across multiple monitors, transfer files, print to a local printer, chat with users, and record the session. The same connection can be used for routine checks or for diagnosing a fault.
In TeamViewer Host, devices are assigned to accounts or groups, permissions decide who may connect, and two-factor authentication can be required for extra protection. Removing a person from the account withdraws their access to every assigned machine at once.
