What Is Signal?

A signal may be a messaging app that permits fast messaging over the web. Like other messaging apps, the service isn’t tied to your service plan as SMS texting is. As long as your phone is online through cellular data or Wi-Fi, you’ll use Signal to message people.

For the fundamentals, Signal may be a lot like other messaging apps you’ll have used. It supports text chat for one-on-one or group conversations. You’ll send pictures, videos, and voice clips inside your chats. Signal also supports live voice and video calls inside your chats for real-time communication.

Signal also includes extras like stickers and, therefore, the ability to share your location with your chats. Most people should be conversant in the majority of its features.

How does Signal work?

In Signal, you want to set a security PIN after installation and grant the proper permissions. Because of this PIN, your Signal account is encrypted within the appliance servers so that once you use it on another device, you’ll recover it alongside your aliases, your groups and your blocked people.

Besides that, the operation of the app is extremely almost like WhatsApp and Telegram. Why? Because Signal detects your contacts who also use the appliance, you’ll be ready to send them messages. In conversations, you’ll have the likelihood to form voice calls, send audios, send photos, or send GIFs, files, contacts or your location and more.

What features make it so special?

Signal has several features that make it stand out from the multitude of messaging apps that teem in the Google Play Store.

Message self-destruction

Signal allows you to configure self-destruction of messages you send. That is, it allows you to configure a period of your time between 5 seconds and every week so that the messages you send are automatically deleted.

Using the PIN

The PIN that you enter the primary time you open the appliance (you can change it whenever you wish, be careful), it’s far more important than you imagine. Why? Because it is an encrypted PIN and chosen by you, not even the appliance creators can access this information.

Blur photos

Another great feature of Signal is that it allows you to blur photos to send them without revealing people’s identity. That is, you’ll not need to use Photoshop or any image editor to blur a face during a photograph. This is often a useful feature for those that take photos at protests and need to take care of the anonymity of participants so that they’re not retaliated against.

End-to-end encryption

Signal uses an end-to-end encryption protocol by calling Open Whispers Systems altogether its communications. This suggests that the messages from your mobile are already encrypted and are only decrypted once they reach the recipient’s mobile. Because of this, if someone observes them along the way, they’re going not to be ready to read them. Although it’s hard to believe, WhatsApp decided to implement this on its platform when Signal started using this sort of technology.

Signal versus WhatsApp, Telegram and others

Do you want to use the initial secure messaging application? So you ought to keep subsequent in mind.

  • WhatsApp collects a fair amount of your metadata like IP addresses, dates of use, phone and model, network operator, telephone number, unique device identifier, location and contacts. By analyzing this information, even without having the ability to read the content of every message, fairly close assumptions are often made about who you’re lecture and, in some cases, what.
  • Since Telegram is cloud-based, technically, all of your messages, photos and files sent in non-private conversations are stored (but encrypted) on their servers. Similarly, it’s not very clear what metadata they collect additionally to your contacts, devices and IP addresses. Of course, these are kept for a maximum time of 1 year.
  • Among the three tools mentioned, Signal is that the only application that minimizes the metadata it saves. Just archive the last time you connected (the day, not even the time) and, therefore, the telephone number of your account. Because of this, you’ll use Signal with the peace of mind that your data won’t fall under the hands of others.

Keep Your Communication Private With Signal

There’s no reason to use an insecure platform for your private messages. SMS texting doesn’t offer any security, while apps like Messenger allow Facebook to read what you say. A signal may be a good way to avoid these concerns while also enjoying a smooth messaging experience.
