However, if you’re texting or conversing online, things are a bit different. Your messages may be accessible to the government, your mobile service provider, or bad actors if they are not end-to-end encrypted. Getting the encrypted texting software Signal is a simple way for everyone to improve their security.
According to the BBC, Signal was launched in 2014, more than ten years ago, and as of 2022, over 40 million users were using the app for encrypted chat.

Following this modification, Signal saw a spike in new users and a brief outage as a result of the influx of users. A few days following the policy change, Signal was downloaded around 1.3 million times, according to Apptopia, an app-tracking company.

Either your given name or a nickname can be used. Signal claims that because your profile—which includes your name and photo linked to your phone number—is encrypted, it is unable to determine the name or photo you have chosen.
