: TeamViewer 12 received positive reviews from critics and users alike. The software was awarded several prizes, including:

Users could remotely access and control computers from other desktops or even mobile devices.

Security has always been a priority for TeamViewer, and version 12 reinforced this. It utilized RSA 2048 public/private key exchange and AES (256-bit) session encryption. However, it is worth noting that TeamViewer 12 also marked the beginning of stricter licensing enforcement regarding the "commercial use" detection, which frustrated many personal users who found themselves kicked off the network for what the algorithm determined was commercial activity.

This was not merely a cosmetic change; it improved usability. The new UI made the distinction between "remote control" and "file transfer" clearer, and the management console became more intuitive. For IT administrators managing dozens of devices, the streamlined dashboard reduced the cognitive load required to navigate the software.
