Open multiple connections in different tabs:
Protect your TeamViewer account against unauthorized access with two factor authentication, just in case your password happens to land in the wrong hands. With an established authentication app (e.g. Google Authenticator), you can simply generate a security code with your smartphone. Both the code and the password are requested during login. With this two factor authentication, TeamViewer helps you meet HIPAA and PCI DSS requirements, among others.
Open multiple remote sessions in tabs, just like in your browser. For an optimal overview, you can also open all the monitors belonging to a remote computer in separate tabs. You won't miss a thing because opened tabs will always flash when new activity occurs on the remote computer, e.g. a new chat message from a customer.
Do you want to ensure 24/7 access to your computer without having to leave it running all the time? With the new Wake-on-LAN feature, you can now wake up your computer remotely whenever you need access. The wake feature simply works via another computer using TeamViewer within the local network or via a router.

Copy and paste files, images, and text via the clipboard:
Copy files, folders, images, screenshots, text, and tables along with formatting from one computer to another via the clipboard. E.g. attach a local file to an email being sent from a remote computer..
Simplified file transfer without establishing a connection:
Send files to computers and contacts from your list without first needing to establish a connection. Using an FTP server to share large amounts of data or files that exceed your email attachment size limit is now a thing of the past. Starting now, simply use TeamViewer to share files with colleagues or customers in the blink of an eye.
Process customer cases in the service queue together with your team:
Now organize instant customer support in your team more easily. All service cases are collected in your service queue and identified based on a session code. You can now manually create a new session code and pass it on to your customer in the form of a link. Instead of sharing the TeamViewer ID and password, like you used to, the customer can now join the session directly with just a click. Alternatively, a code is created automatically, as soon as the customer launches your customized TeamViewer QuickSupport. In this way, new customer cases are added to your service queue.
TeamViewer API for integration into your applications:
Integrate TeamViewer with your systems, such as helpdesk, ticket, or CRM. The new TeamViewer API offers the option of seamlessly integrating TeamViewer functionalities into your own work environment
Automatic synchronization of TeamViewer accounts for the users you manage, e.g. with Active Directory.
Automatically import reports into your own software, e.g. connection logs or bills.
Import user lists from your company environment into the Management Console.
Use service queue functions directly in your own software, e. g. session code creation.
