How to Use Tox to Chat with Your Friends and Family?

Tox is decentralized, end-to-end communication.  There are no central servers to store user’s message whatsoever.  You need to create a profile when you use Tox on a device. In other words, this profile identifies your device rather than yourself.  Every Tox profile has a 76 hexadecimal characters as the Tox ID.

So you have to download and install a Tox client on your computer (qTox or uTox), on your phone (Antox or Antidote) and then create a profile and you will be able to chat with your friends and family.

How To Add friends on Tox Client?

As I’ve said, the Tox ID is a 76 hexadecimal characters that identifies your device. To add a friend, you need to enter these characters into the add friends text field.

But who in the world can remembers such long characters? The account resolution service comes to the rescue! This service can translate those 76 characters into email addresses such as [email protected] which is much easier for the human brain. This is very similar to the DNS service.

Which Tox Client Should I Use?

Currently, qTox is the easiest and has more features than other Tox Client. qTox can help you capture the compute screen, send files to your friends. You can also do voice call and video call with qTox. If you are a Linux user and use different computers very often, then install qTox. qTox is also recommended for Windows and Mac users. Android users install Antox. iPhone users install Antidote.
