Private SMS and instant messaging app

Signal Private Messenger APK  is an open-source messaging mobile application that can be used as an alternative to the Android’s messaging app. The internet-based chat app protects its users with end-to-end encryption, while non-Signal users will receive an unencrypted text message or SMS. It also features a voice over internet protocol capability for users that want to talk via voice or video chat. Advanced and professional can independently audit and modify the app. 


Is Signal Private Messenger safe? 

Signal Private Messenger keeps your instant messages safe by using a series of protocols. These are the Extended Tripple Diffie-Hellman key agreement protocol, Double Ratchet algorithm, Curve25519, AES-256, and HMAC-SHA256. By implementing these to create end-to-end encryption, the content of your messages can only be seen by you and the intended recipient. This is opposed to Signal servers accessing and storing your messages. 

They can use it for company purposes such as generating specific advertisements to both users. You also have the option to lock messages and notifications with a passphrase, and use the incognito keyboard as you create your message. This adds an extra layer of privacy from the app’s server as it will not be allowed to use machine learning to create predictive text. 

Messages that are extremely sensitive can be sent via the Disappearing messaging feature. This means that your text will disappear from the chat after a minute after sending it. As a preventative measure, you can verify your contacts via a safety number or fingerprint key. The feature compares the information with other Signal users, and verifies a person that a user has delivered his unique password. 

How to use Signal Private Messenger?

Signal does use your mobile number to confirm your identity, but it will not have access to your phone’s contact list. Should you also switch phones while registered to the app, you can still access your messages and connections once you’ve provided your login credentials. The program does require its users to connect to the internet or have access to mobile data. 

This is how you’ll be able to avoid the charges from texting. As for Android users, you will need to have Android 4.4 or newer to be able to install this app. Once you launch the app for the first time, it will request access to your contact list and media files. This is so that you can begin contacting friends, exchanging messages, and making secure calls. 

The next page is where you will type in your mobile number. You can allow Signal to view your SMS messages, or deny it. Denying it will prompt it to send you a six-digit verification code that needs to be entered into the app. Once you’ve been verified, you will be able to create a profile with a display picture and a user name. You will then be able to set Signal as your default SMS app after you’ve finalized your account. 

Superb privacy conversation app 

Signal Private Messenger is suitable for users that want to streamline their text messages and chats into one application. In addition, it is also fitted with multiple layers of protocols and keys that will keep your messages safe from prying eyes and the developer’s servers. Overall, this app ensures that you’ll be able to organize your conversations in a single secure space.
