The Signal is simply a messaging app like WhatsApp, iMessage, Facebook Messenger. Signal, an encrypted messaging app, has been in service since 2015. But became even more popular with the May 25 murder of George Black Floyd, a black man in police custody.
The assassination sparked protests against apartheid around the world, including in the United States. Because the signal app is a secure or private messaging system, many protesters are more likely to use it to exchange messages than other communication methods.
Today, however, the Signal app has gained the favor of technology giants, cybersecurity experts, journalists, government officials, and many more.
The Signal app is available as a free app for Android, iOS, Windows, Mac, and Linux. This service is also available for free for browsers, including Chrome.
This app is becoming very popular today due to the different security protocols available to the users through this service.
It also includes all the basic messaging tools you need (read receipts, emoji support, group chats, voice, and video calls). Like WhatsApp, the Signal app uses your mobile phone number to identify you to your contacts, so there are no more usernames or passwords to remember.
The Signal can also be used to send regular SMS (SMS) and MMS messages on Android. However, Google has decided to offer this feature as a chat feature to the Google message app used by many users around the world. As a result, the Signal app will face a lot of competition shortly.
Usually, your phone number is using to verify your identity and the setup process of an app. After entering the number, a code will be send to your phone number as a message to verify your identity.
Then you need to enter a four-digit PIN for further security verification.
Among the unique features of this messaging app is setting the setting to delete individual conversations after a certain time. To enable this feature, you need to click on the user profile and toggle the “Disappearing Messages” feature.
Is Signal safe?
Another reason why this app has won the trust of everyone is that it has been created as an open-source. Because of this, all the security vulnerabilities in it are fixed very fast.
It also does not belong to any major technology company, such as Google, Facebook, or Twitter, and is set up as a non-profit organization.
It does not need to sell its users’ data or use it for targeted advertising to generate revenue or make a profit.
