Video: Secure Business Messaging with Threema Work

Instant messaging not only facilitates communication in private life but also in the business environment. However, even if it’s convenient and efficient to use regular chat apps for communication with work colleagues and team members, confidential company data should only be shared using services that provide sufficient security and privacy compliance. Companies do well, therefore, to ensure that instant messaging at work is on the right track.

Our new promo clip illustrates why a secure messenger is indispensable for companies and what benefits Threema Work offers:

Pay Threema’s Android App with Cash and Remain Anonymous

Threema being a paid app is a feature, not a bug. As they say, there’s no such thing as a free lunch, and in contrast to paying with user data, paying with money is transparent and doesn’t sacrifice privacy.

While paying with money is good, paying with cash is even better. Despite the general trend of abandoning cash in favor of electronic payment methods, Threema’s Android app can now be purchased with paper money. It has always been possible to pay Threema for Android in privacy-friendly fashion using Bitcoin, but cash payments now allow for complete buyer anonymity without cryptocurrency.

How It Works

  1. In the Threema Shop, you select “Pay anonymously with cash,” order the desired amount of licenses, and receive both an order number and a “license URL.”
  2. You send us the due amount in cash and indicate your order number.
  3. After receipt of the payment, we activate your licenses, which you can then obtain via the license URL.

Individual Chat Wallpapers in Threema for iOS

Each chat tells its own story. To also highlight the variety of your conversations on a visual level, Threema for iOS now allows you to set individual wallpapers for each contact or group chat.

Not only does this give the app a very personal touch, it also makes immediately apparent which chat is open, minimizing the risk of accidentally sending a message to the wrong person or group.

To change the wallpaper of a chat, simply open the respective contact or group details, tap on “Wallpaper,” and select an image of your choice.

World Press Freedom Day

In modern democracy, the press plays such an essential role that it is often described as the “Fourth Estate.” Without independent news coverage, and thus without the watchdog function of the press, political processes could not be reviewed by the public.

Open Letter to the British Government Regarding the Online Safety Bill

In addition to the EU’s so-called “chat control,” there’s another European draft legislation that uses child protection as a pretext for full-scale surveillance of chat communication without probable cause: the UK’s Online Safety Bill.

Data Protection Is More Than Just Encryption

Online services have started to realize that more and more users care about privacy. As a result, many put an emphasis on privacy protection in their marketing. More often than not, however, privacy protection is confused with security or, specifically, encryption. While encryption of user content is necessary for comprehensive privacy protection, it is by no means sufficient. If, for example, a chat service end-to-end encrypts the messages users exchange but at same time requires personally identifiable information and collects metadata for marketing purposes, that’s nowhere near comprehensive privacy protection.

Statement on ETH Findings

Last year, a student at the Department of Computer Science at ETH Zurich wrote his master’s thesis on Threema’s communication protocol. ETH Zurich has now published his work as a paper/preprint. The presented findings have been addressed or no longer apply to Threema’s current communication protocol “Ibex.” None of them ever had any considerable real-world impact.

A Decade of Seriously Secure Messaging

Threema for iOS: Preview of Upcoming Multi-Device Functionality

With the desktop app and the web client, it has been possible to use Threema on the computer for a while now. At the moment, the desktop app and the web client require an active (end-to-end encrypted) connection to the mobile device. To send and receive Threema messages on the desktop even when the mobile phone is turned off, a multi-device solution is in development.

Starting today, a tech preview of Threema 2.0 for desktop is available, which allows iOS users to test the upcoming multi-device functionality ahead of time. To use the responsive new desktop application, which was redesigned from the ground up and is based on a totally new architecture, you will need the multi-device beta version of the iOS app.

Test the multi-device functionality now

At the moment, the tech preview of Threema 2.0 for desktop is only available for iOS, not for Android. In the future, support for multiple linked devices, including tablets and Android devices, is planned.
