Teamviewer uses AES 256-bit encryption, which is a recognized high-quality standard, and also used by NordVPN. It’s a pretty sensitive function that requires high-level security, yet millions of people trust Teamviewer and use it regularly due to its functionality and usability. You can let someone do that with a single click. However, its primary function is to allow someone else to take over your computer remotely, for example, to fix an issue or install a software.
Teamviewer is the online collaboration tool that allows you to remotely control other computers, share your desktop, organize online meetings, and share files.
