Signal: the best encrypted messaging for Android and iOS?

Despite its two billion users, WhatsApp is losing ground against its competitors. It must be said that between very dangerous malware like Pegasus and Predator, the various indiscretions at the level of metadata, the threats of banishment and the scams of all kinds, many users change creamery. In the category of end-to-end encrypted messaging (that is, “where no one can read messages”), there is not much to choose from.

Dubbed by the whistleblower Edward Snowden who is the authority when it comes to confidentiality, Signal does not keep any metadata on the exchanges. So of course, the messaging offers groups of “only” 1000 people and there are no funny “stickers”, but it will suit 99% of users. All you have to do is convince your friends to migrate to Signal, but maybe they are already there …

To take advantage of portability, you have to create an account on your mobile, install the computer version and link them together. Not very rocket science.
