One of the features of this option is that, even if the mobile phone does not have a battery, tablets or computers can connect to the application independently and synchronously. Of course, maintaining the same level of privacy and security.

In this sense, every device has the ability to encrypt messages, calls and video calls without resorting to the help of a mobile phone. In addition, the user will no longer need to verify his / her identity every time he / she needs to log in, as he / she has “Automatic device verification”.
