Taking care of your security with Threema messenger | Onlinesim

Threema is a message app that focuses on security and privacy metrics. Threema tops the list of downloaded apps, surpassing WhatsApp, Instagram, and Facebook in its time. Threema is available for download for Android and iOS phones in the Google Play Store and Apple App Store.

The message app was created by Swiss developers, Threema GmbH, paying more attention to information security with user privacy. Threema is a paid app priced at €3.99. In addition, it is available for use from any browser and has a version for desktop computers.

The app stores minimal data on servers in Switzerland, and the rest of the information, such as an account with conversations, is stored on the mobile device. It turns out that the servers work as an intermediary for sending SMS, which is similarly amenable to encryption. Threema does not synchronize data in the cloud to not succumb to hacking, which makes it even more secure for users.

Features of the Threema messenger

The main advantage of Threema is considered to be its exciting registration. You can't sign up for the app by mobile number and name. And then what to do? To register, Threema assigns each user a unique and anonymous ID - this is the only information stored on the app's servers.

Also noteworthy are the three dots of different colors below the contacts. What are they?

  • Red dot - the app does not get a conviction as to whether the contact is a natural person.
  • Yellow dot - the phone number/email is valid.
  • Green dot - adding a contact is due to Threema's built-in QR code (users themselves create a QR code that other users scan to add a reference). Different settings like email address and phone number can be skipped because the app doesn't need to know this. You can use the service anonymously because a random ID will be responsible for all the security.

Other benefits of Threema app free include:

  • voice calls,
  • video calls,
  • sending voice memos,
  • sending files (photos, videos, PDF, GIF, DOC, and many others),
  • creation of groups,
  • light/dark mode.

Installing and configuring Threema for iOS & Android

Installing Threema from Google Play and the Apple App Store is easy. As soon as the app is launched for the first time, a personal Threema ID must be made. To do this, the user needs to swipe the highlighted display area, which will help generate an ID and create a unique asymmetric key (such keys will appear in duplicate) to play a role in SMS encryption and decryption.

A copy of the user's public key will automatically remain on the application servers - people who start communicating use that same key to encrypt messages. The user's private key stays on their mobile device, so Threema doesn't see it, just like other users.

Using Threema won't be too tricky if you've dealt with the Whatsapp app before. The application functions on Android and iOS phones ideally and without problems.
